I posted this in the prop section, but think it may be better here. Any tips are greatly appreciated.
We have located a possible replacement engine
for our Gulf Island 29. Originally there was Ferymann A-30 with 2.10:1 gear
installed. The previous owner pulled it out on its last legs, claiming it was very underpowered.
The boat is fitted with a campbell 3 blade
13" - 12 prop.
we have our eye on is a Yanmar
3HM35. I realize this is pushing the limits in terms of size for the boat ( it will fit). Do people think it is far too big? I have seen a few other gulf island 29's with 20-30 hp's. I have also seen an Alberg
30( which is almost the identical boat) with this exact motor
. The gear
is 2.14 :1.
Unfortunately, the 13" prop appears to be about the maximum diameter for the aperture.
What are peoples thoughts?
