5.8m trailcraft trailblazer with 200hp?

 just wanted some opinions, i have just bought a boat from over east for a good deal and is on its way home


just thought a yamaha 200hp 4 stroke on the back seems a bit over the top, the plate on the boat says it can take one but it seems like a lot of engine for a boat that size


should i worrie about downsizing and saving on fuel ?? the owner says it will do 30l an hour at 25kn, is that not too bad?

Remember you wont be using

Remember you wont be using full power very often, so moving to a smaller engine to save fuel wont actually do anything. Or if it does offer a tiny saving in fuel, the price of changing engines will far out weigh any fuel savings.

 Should also add they way you trim your motor, distribute weight in the boat, and how hard you want to push would have a far greater influence on fuel consumption.

Sat, 2017-10-28 12:47

 Not at all, more horsies  the better. Extra weight will help it ride better and you have the power there if you need it.

Reassurance that you can load the boat up with gear and boys for a trips out deep knowing you have the power and torque to keep the boat trim.

Agree with others

Agree with the others. If it's rated to 200hp, keep it on.  Cost of changing not worth it.  Trim and weight distribution still important to your performance.  

Would love to know what WOT is.  I've got a 5.8 Coraline with 135hp and get 37 knots, which is heaps and have only managed to flat stick it a couple of times.  You'll be absolutely flying.  Wonder if you can change the prop.  Engine wouldn't really be working very hard, so maybe something with a different pitch may get you cruising at lower rev's and therefore less fuel burn.  My knowledge isn't great in this area, but maybe others can provide some suggestions.

 ok thanks for tips! my first

Sat, 2017-10-28 13:24

 ok thanks for tips! my first thought was sell the 200 and get a lesser used motor and save that way, but i am sold on keeping it now.


i will be playing around with props for sure, wont be here untill the 16th of nov at the earliest. ill let you know how she goes when it gets here!

 200 seems alot for a 5.8m trailcraft which is the same 5.6m version. I have the 660 trailcraft max power is 200hp. I have a 175hp and it's spot on. Max speed 33knts balance is sweet drifts well in choppy conditions. If your handles the weight of the 200 you will love the extra power but if the transom  sits low the choppy days could be a problem especially with passengers & all their gear.

 Got a 6.6m sportcab with 225hp on it is perfect.. does have a 350l fuel tank along with 90l fresh so fully loaded she will weigh a fair bit. can never have too much power but can always be under powered. Leave it on there, you will always feel confident with those extra horsies up your sleeve.

 I had an older 5.8. 2002 I think.

Not sure how they relate to yours but Im thinking its same as mine was rated 200 as well.

Mine had a F115 Yam and was good except when fully loaded for Abrolhos then worked hard but still 29 knots.

Id think 200hp at full power would be pretty flighty if lightship, but OK if you are experienced and careful, if will fkn fly on flat water and on chop it'll LITERALLY fly

The older you get the more you realize that no one has a f++king clue what they're doing.

Everyone's just winging it.

Sat, 2017-10-28 17:37

 As other have pointed out, play with the weight distribution. I added 80kg of river pebbles from Bunnings in the anchor well and nose of my 6m stesll as the early Honda 4banger, rear dual batteries and live well added a tone of weight to the rear. You could see that the arse was sitting really heavy and the broader part of the hull was taking the chop/slap making for a very uncomfortable ride. Back breaking!

With 80kg in the bow the boat sat and road 100% better. We always tried to load gear towards the nose too. It was still a bumpy ride but chalk and cheese compared to before.

 this gives me an idea! i will weld up an ally storage compartment to tightly fit in the front section, was thinking ill put a consealed section  inside it and fill it with led.

that is if the boat doesnt sit well in the water

Not Lead

 Maybe not lead.  Lead will corrode aluminium.

i had a 5.7 mt with a 115  2 stroke with no problems of power ,  I would first check what is stamped on the hull for maximum HP.   I bought a 6.4 which was only stamped up the 150 hp.   The yard put a 175 verandah on and they said they would just re stamp it to suit the motor , which is great until you have an insurance claim ,   Check what the manufacturers specifiy the maxi Hp is and go from there   IMO

 yep thats what i reckon. nothing like having maximum power and coming home at 40+ knots on those glass off days. even more fun when you drag your mates on the biscuits behind the boat.

Mon, 2017-10-30 08:47

waterbottle is better than lead etc if u got space or 20 l spare fuel  move batteries forward

a you have spare water in emergency -if its fresh

b u can take some out if u got loads of gear / people on board

c its cheap

if u go this way keep bottle/container as full as u can

- to minimise free surface effect

 Im pretty sure you will find that the engine on that boat is not a 4 stroke, looks like a Yamaha HPDI 2 stroke. cowling shape is different as well as it appears to have the red stripe above the anti ventilation plate which indicates a 2 stroke engine

Hmmmm... You’re on the money with cowling vents, clearly different from the 4 stroke. No idea about the red line though.

Think your right there

Mon, 2017-10-30 20:07

Think your right there Johnny. The red stripe and the HDPI have that black section just below the air intake on the rear of the cowling. Also says High Pressure Direct Injection intead of four stroke on the side

Much lighter than a v6 fourstroke and the 200hp HPDI had a pretty good rep didnt it?

 That  would also explain  the fuel  burn. I'd imagine  your get  better than  30lph on a 200hp 4 stroke /5.8m trail craft.

your correct i have made a boo boo, i honestly assumed it was fourstroke. based on the cowling. i know the carby two strokes looked way different. 


do you think i have over compensated the value of the boat as a whole?


i dont mind two strokes at all, they have pros and cons, i probably wont have issues with weight like stevo said. just more concerned about resale value! 


do these direct injection 2 bangas do similar hours to the fourstrokes with regular sirvicing?


thanks all

 Definately worth less than a 4 stroke. Will go a lot harder though. Mate has a 250 hpdi on his haines. Goes very well and has given very few problems. Make sure you run the genuine yamalube. It likes it much better.


Does anyone know where the love of god goes, when the waves turn the minutes to hours?

Oil mix

 Now you have realised its a 2 stroke.  Better find out where the oil mix goes before she stops running

If never owned a 4 stroke

Tue, 2017-10-31 07:11

I'm a moron! My last motor was a 90 yammy

Went pretty hard. 


I still believe I'm on top if I sold it in perth

After shipping rego and a few mods I will spend $27500


Think I'm still doing Ok?

Don't stress about...

Tue, 2017-10-31 08:12

Don't stress about... It's done now. I bought a 2003 4stroke Honda for "4 stroke reliability" and ended up with a massive repair bill before even hitting the water due to a missing o'ring on the starter motor. I know that empty pit of the stomach feeling though!

How many hours has it done? Did you get then engine mechanically checked by anyone?


Resale is good but its smiles that add more value to your life!

If you're buying it to make a profit as a business decision, then you've probably stuffed up... If you're buying it to own and enjoy a 200HP 6m fishing boat then you've done just fine!


To hire a boat like that would cost you $400-450 per day. A charter trip is $250 a day and you might have to spend the day fishing with d*ckheads. Make sure you take it out at least 4 times per month until you hit the breakeven point 

If you've got kids or family to spend time with then the value of owning a boat in WA is unquantifiable, in my opinion anyway

 Thanks mate. Defenetely not a business plan

The previous owner has plenty of sirvice history for me!

It's done 700hrs, which doesn't bother me toooo much.


I took a risk buying from over east.

But I justified it by seeing similar boats on the market and what I have looked at so far. You don't get much for a 28k budget in perth unless your lucky.


Plan to strip the boat and tidy her up too.  Should be I Gooden once I'm done with it


Can't wait till Its here.

Tue, 2017-10-31 07:44

 The small block HPDI were really good, we had one on our Seafarer Vagabond and we could do ocean reef-Thomson's bay-lap of rotto-ocean reef on 45L

it was amazing on fuel, give me a yell if you need a service or anything, we put 900 hours on our one before we sold the boat and it never had any issues.

200 hp on a 6m boat

Tue, 2017-11-21 23:36

Are you sure you are not imitating the Caspian sea monster (first of the high speed WIG design craft). We will no doubt see you coming from miles away by the low fling you will be doing. But heh, isn't it great fun, have a great time and look forward to one day seeing you on the water or ramp.
