60hp mercury 4 st prop selection?
Hello all, hoping some of you can help me out with your own experience.
As the title suggests I'm looking for a prop to suit a merc 60hp 4 stroke that I recently repowered a Hinton 4.5m runabout with, Hinton is a direct knock off of the Haines 445r.
The motor is still being run in so I can't tell you what my current max revs are, but I can tell you I struggle to get on the plane with the factory 3 blade, once it's up it goes well until it drops off the plane which happens easily. I slowly climb on the plane at about 3200rpm and 12-15kn at 4500rpm I'm doing 22-24 kn
Anyone else have the same motor/445 hull combination, if so what size prop are you running and what set of holes are you mounted on? I'm thinking I may lift the motor another hole
Thanks in advance
Josh

hi there , i have the same
hi there , i have the same outboard on a heavy 4.5m plate boat.
I have experienced moments of danger when heading out throu reef in the n/w when loaded up and have found it hard to get the hell outa there(around breaking waves)!!
Having changed props to a solars it has helped but not fixed the problem .
I have found out that the mercs do have a higher top end but are not as solid out of the hole so to speak.
This has made me think that a 70hp yammi would be handy as they are around about the same weight but have better punch.
Perhaps a 4 blade stainless might help??.....
will give you prop sizes later.

Spend lots of time and money playing props
Just propellers helped me out heaps i had to wait for a batch to be made in the size i wanted
I tried it in ali first what differance planes eash now
getting the bottom line final answer from a bunch of blokes that use false names and put smiley faces at the end of paragraphs is not the best place in the world to get the information you seek.

Now I'm thinking
I have a 4.5m ally craft with a 60Etec have fitted fins and put a 100l fuel tank just forward of middle...(centre console) better then it was getting out of the hole but could still be better...maybe a4blade prop would complement other tweaks...when planning she steams along nicely
