Re: 255 Conquest Re-power with SUZUKI 200 APX Twins
[T]ook out the [255 CONQUEST] today with five adults and a small child onboard. The [twin Suzuki 200 APX engines accelerated to] 5,800-RPM. Top [boat] speed was 37-nautical-miles-per-hour into an [opposing current from] tide. I am very happy with the performance of the 15-1/4 x 22-pitch four-blade p...

Re: 255 Conquest Re-power with SUZUKI 200 APX Twins
The props we are testing are:
--Suzuki 4 x 15 x 20
--Suzuki 3 x 16 x 21
So your thoughts are correct: 22-pitch might be too big.
Cheers Greg

Re: 255 Conquest Re-power with SUZUKI 200 APX Twins
WOW--Thank you so much for the detailed replies.
The on-water test is tomorrow.
Yes, the engines are counter rotating engines. These can either spin-in or spin-out
Going for the traditional "out first up."
I will post up the results later.
Many thanks

Re: 255 Conquest Re-power with SUZUKI 200 APX Twins
Also [the 255 CONQUEST] liked to run faster; it fell off [hydroplane] around 17-nautical-miles-per-hour.

Re: 255 Conquest Re-power with SUZUKI 200 APX Twins
Thanks for you reply. The boat is a [2002] 255 CONQUEST. The old engines were Mercury 150 OptiMax with 17-pitch propellers. Top speed was 30-nautical-miles-per-hour, [and the engine speed ] couldn't get over 5,100-RPM--over-propped in my opinion and terrible on fuel and oil. [The 255 CONQUEST] is ve...

255 Conquest Re-power with SUZUKI 200 APX Twins
I'm in the process of putting twin Suzuki 200APX engines on my [255 CONQUEST].
[I am deciding between propellers with] three-blades or four-blades and their pitch.
I mainly go angling offshore at 30-miles-out and troll at 6- to 7-nautical-miles-per-hour.
Any thoughts?
Cheers Greg

255 CONQUEST Install New Cables to Hardtop
I need to run a new cable up to the hardtop [on a Boston Whaler 255 CONQUEST boat]. Looks like I need to remove the hard shell roof liner. Any tips on how to achieve this without any damage? Many thanks .
