I have found 13hp Yanmar industrial engine at an online surplus supplier for what I believe to be an unbeatable price: $779.95, + shipping etc. Here's the link (copy and paste) -
This fixed-speed engine comes without alternator or cooling, but I believe the parts can be found to make it work in a marine application.
Using this engine as the starting point, I'd like recommendations for a hull design for the following use:
Fishing 2-4 people in most sane sea conditions (3-5' chop, larger rollers, rain wind, etc.)
I'd like the boat to accommodate the following features:
A wheelhouse (low would be ok), stowage for about 200lbs of fishing gear and supplies, 2-300lbs of additional gear (batteries, anchors, etc.)
6-8 knots would be fine.
Is this too much to ask of this engine?
