OK, I have a 2008 3YM20 in my
boat. The PO re-powerd to to the 20 rather than the 30 to save a few pound for
racing.... Don't ask. So now I have a 18,000#
boat with a small aperture (13"
2 blade - might be able to get a 14"; need to measure) Is there any way to "aftermarket upgrade" the
Yanmar the way my brother does his Cummins pickup truck? I have not been able to make 2/3
hull speed, and in rough
weather I can't point it into the
wind - annoying. It's not a huge issue, as I really don't use the
engine except for the last 1-3km from the harbor, but still, nice to know I have it if I need it....
Thanks
