Trim tilt Evinrude.
Submitted by Coben13 on Thu, 2015-08-27 17:07Hi all you mechanics. Have got a trim tilt motor from Wade. It looks similar except his sits in behind the motor where mine sits to the right hand side. I am thinking I can just change the whole mount and trim tilt. Will it work? Seems the same motor. See Evinrude trim tilt.

Obsession hardtop And home made outriggers
Submitted by nico on Mon, 2015-08-24 21:14Hi Guys,
I told you in my last post I was go build a hardtop, well all done smashed it out in a couple of days
I knocked up a timber jig from pine and ply with frames shaped to match the aluminium frame to support the top so I could get the camber to match. Bought my 10 mm Corecell which is a composite foam ( rebuilt our whole boat with this product) from Kirkside Fibreglass in Ozzi Park stapled the sheets to the jig and glassed one side at a time. I would have liked to set up a infusion pump and vacuum bagged this for a real light weight product though as this is a very budget rig on a shoe string budget it wasn't to be.
By the time I had it glassed with chop strand mat and stiitched cloth,rolled on a flow coat finish it weighed about 24 kg not to bad considering it is 2m x 2m with no bracing except for the alloy frame.
Decided I may as well completely finish this project and made my own outriggers as well bought some reelax bases and got hold of some rod blanks and made the poles just have to rig them up now. So she is officially finished just have to do a gelcoat respray on the forefoot at some point, think that can wait till next winter. Now it's time to join Perth game fishing club and get in to the fishing scene.

DIY Gelcoat Crazing Repair on Bottom of Hull
Submitted by Tradewind on Mon, 2015-08-24 10:10Hey All,
Doing a bit of maintenence on the boat at the moment to spruce her up a bit.
She's an old Chivers Thunderbird and the next part of doing her up is addressing the spider crazing on the gelcoat on the bottom of the hull
I could just leave it but i'm looking at possibly selling it in the coming year or so, so i'd like to have it tidier
I've researched it nearly to death and it seems the best way is to expand the cracks, clean and then fill with Gelcoat putty filler and sand back
Some say use the cone shape burr from a dremel, some say use a church key to open it up (Don't know how to get my hands on one of these)
I'm hesitant to use the dremel as i'd be upside down and wouldn't have proper control and those tools can rip through fibreglass like butter
Anyone had experience in doing similar and want to weigh in on their experience?

2nd battery question....
Submitted by randall df223 on Sun, 2015-08-23 18:47I think my number two battery has died. Its is flat as a tack but i cant get a charge to go through it. I suspect its in need of replacing.
Both batteries are cranking batteries connected through an isolating switch that can select #1; #2; both; or off.
Down the track i want to introduce a deep cell battery for my house electronics and one of those fancy switches that puts the charge straight back into the cranking battery and then switches the charge to the house battery.
If i introduce the deep cell battery now, without changing the switch, i am just limiting myself to one battery, arent i? The deep cell battery wont be of any benefit because it wont have the cranking power to start the motor if the cranking battery fails for any reason...
I suspect i know the answer already... putting in a deep cell battery without the proper switch isnt going to give me a back up cranking solution, is it?

After looking around the missus suggested getting something bigger in maybe a quintrex, I know they are a mass produced boat but we/she & the two kids (4yo 6yo) have fallen in love with a 2006 freedom sport 610 with a 150 4st yammi... Done 57 hours fully optioned out along with trim tabs (USA brand know nothing about them... Stainless flaps) has anyone Owened this particular boat with a 150 4st... How was it in the chop and a following sea and out wide if you ventured that far? Will be used for crabbing, squidding, insore fishing, and the occasional out wide fishing and family trips to rotto...

Replacing battery cabling
Submitted by Cruise Control on Thu, 2015-08-20 10:49Hey Guys
Looking for mobile marine sparky south of the river to do some work for me, I am in Forrestfield.
I am currently getting some power "leakage" through my battery isolators. After I switch off all power I seem to have some residual power coming through to some instruments. After some time the "leakage" stops and all power is isolated so a problem somewhere. Given that the setup is 13 years old, its probably time to replace with something that I can absolutely rely on. At the same time I would like to wire in a house battery to provide power to Radios, sounders, lights etc. This needs to be isolated from starting the engine and should charge up after my starting batteries are topped up. This is all a little beyond my "auto electrical 101" experience, so looking for someone to a good job.
Any recommendations or if anyone is interested can you please pm me to discuss ?
cheers

Drum or windlass anchor winch
Submitted by Doooma on Wed, 2015-08-19 09:36looking at upgrading my anchor winch on the Commodore Abrohlos 8000, as the one that's on there (windlass) looks to be what was originally fitted, can't actually hold the boat... Every time bow goes up she lets out rope and winds out, as if it's not designed to handle the weight of the boat... Also is painfully slow at letting rope out when trying to anchor up on spots.. I mean PAINFUL!
can anyone recommend a decent windlass that can handle a boat probably pushing 3.5 tonne loaded? Or do I bite the bullet and install a decent sized drum winch on the bow..
I do have a viper pro 1000 drum winch sitting in storage I bought for another boat but think that may be a touch small even though they say suits boats to 9m...
I want to be able to safely anchor and fish in water up to 85m depth..

charging batteries
Submitted by Gav475 on Sat, 2015-08-15 20:57I have dual batteries fitted with a colehursey isolation switch. When attaching a battery trickle charger is it necessary to disconnect the leads from the batteries or is it ok to leave them connected when charging and leave the batteries in the off position. Over to the gurus for some advice. Cheers lads.

mercury propeller
Submitted by optimont on Mon, 2015-08-10 19:51Hello fellow fishwrecked people,just wondering if anyone has a 17inch prop to suit a 115hp Optimax. Not fussed if alloy or stainless as I just want it for a spare and an option when running a heavily laden boat.
I currently run a 20inch laser and it works great for top end speed,but a bit slow out of the hole.
Trailer Bearings
Submitted by Cruise Control on Mon, 2015-08-10 13:16Probably a subject done to death but I still have a question or two.
When you replace or repack your bearings, do you fill the whole hub with grease as well as the bearings or do you only grease the bearings ? I have been using Nulon high pressure grease, the red sticky stuff and have found that to be of good quality, it doesnt melt and seems to cope with the water OK. Any other suggestions as to a good grease ?
cheers

opinions on reverse chines please
Submitted by craig scott on Sat, 2015-08-08 17:33I'm looking at replacing my pressed Mako Dory 460 (plate sides, but you know what I mean) with a plate dinghy.
Chasing a sealed floor mainly, for peace of mind flotation wise.
Question is this,
There's a few plate designs getting around now with pronounced reverse chines. They look very nice indeed and look as though they would offer excellent stability, and combined with a reasonable deadrise at the stern, would be a good ride in a bit of slop.
I don't know if I'm over analyzing this, but would the reverse chines make the hull ride harder than without the chines?
It seems to me that on a good impact, the hull would come to a quicker stop once the chine line is met, rather than pushing through and using the bouyancy of the hull to halt the downward force.
Like I said, am I nit picking here?
There's a bit of conflicting opinion on this on various sites. Just hoping someone here could add a bit of real life to my theorizing.
Cheers, Craig.

Mechanic recommendation
Submitted by creamy on Sat, 2015-08-08 06:24I'm looking for a recommendation for a mechanic to change a gimbal bearing on my Volvo Penta Duo Prop leg who knows what their doing (and hopefuly won't make me mortgage my house to pay for it). I live in the Armadale area so would prefer to find someone sor, but highly recommended is more important. I searched but couldn't find recent or relevent results.

Differences 2003 - 2012 Merc 60hp 4 stroke
Submitted by Giddyarp on Fri, 2015-08-07 22:59Hi all,
Still researching my (hopefully soon) boat purchase. I have been looking at a few boats with a 60 Merc 4 stroke fitted, one I really like is 2012, another is a 2003. Other than the age and hours run, are there any major differences between the two year models ? Have done a bit of hunting around and cant find much out.
Thanks in advance for your replies,
Cheers

New setup - trailer advice 15" wheels??
Submitted by Jupri on Mon, 2015-08-03 21:44Hi all,
Just after some advice with a new tinnie rig i am setting up.
Boat is a 3.6m Bluefin Rascal, motor is 15hp 2 stroke yamaha. I have decided on these to keep the weight down as this rig will be beach launched almost every day in cray season and up north on trips as well. I will be towing this setup behind my suzuki jimny and as said launching at beach and also ramps.
I am getting the trailer custom made to match the suzuki jimny it will go behind. So that it will run in the same tracks as the vehicle. I have towed a wide trailer behind my narrow 4wd and it was not ideal. As space is also a luxury with small setups i was thinking of running the same size wheels as the car so i would only need one spare.
Does anybody know beach launch a tinnie with 15" trailer wheels?
Thanks
