Peter, Do you recall any differences on the seawater cooling lines between these engines? I'm having a very difficult time getting new hoses for my 2Gm20F. I was told when I installed it that the engine was 18HP at the crankshaft but 14HP at the prop shaft. I know that Yanmar switched from making them in Japan to making them in Germany. I was also told that to be sure that I specified its origin when I ordered impellors as they were different. Now I wonder if the hoses are also different? For what its worth the data plate on the block says:2GM20FCont. Rating 11.8 Kw 3400rpmMax. Output 13.4 Kw 3600rpm23727 (serial number)Looking at on line images of 2GM20F's show what looks like my hoses but the parts diagram sent from the dealer shows different hoses. This is getting frustrating. I'm afraid to leave the dock because one of the hoses has a crack where it attaches to the heat exchanger. Not in an area that would be easily repaired if it lets go. Any thoughts on this from anyone would be very helpful. Walt From:

I've found the best prop choice (apart from breaking the bank for a folding or self-feathering prop) is a three-blade Campbell Sailer.It has good thrust and relatively little drag ... kinda like dragging a bucket with a hole in the bottom

... and the support from the maker is outstanding.As far as power, my Vega had a 13hp Yanmar 2GMF and Campbell Sailer three-blade 13RH9 prop and would do 4 knots at a fast idle, 6.5 knots flat out, and was never any problem in strong winds or currents. My Ballad has the same engine, but a later 16hp version, also with three-blade Campbell Sailer 14RH7 prop and has more than enough power for these PNW waters.When you look at the blades on these props they are so skinny you wonder how they would generate thrust, but they do, and do it well.Peter
