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....
