Good luck with your boat shopping
...it's great to have choices...
Experience with Yanmar 2gm
18 hp. ...delivery on friends Hunter 33 early last May from Long Island Sound
to southern Maine
... after waiting out howling north
for 3 days in Pt Judith pond made our way into moderate north winds into
Buzzards Bay under motor
alone, boat pounded up bay all day averaging about 5 knots and then continued into canal and up to Kittery, Me. (in light wind) through the night approx. 30 hours straight.
I am a fan of Yanmar as I have a 3gm
in my 30tfer... But was very impressed with the little 2 cyl 18 hp it did not miss a beat and very good fuel
Of course motor
only as good as properly sized/pitched prop.
