2GM prop

[Fred]

We replaced our 1GM with a 2GM in our '81 H27 and I'd like to know what prop is best. We have a 13X10 3 blade and the 2GM easily revs up to 3800 rpm. It seems like we could use more pitch and/or diameter.

I have the sanme boat and engine, changed my prop to a 14X13, works great.

Tom: Much thanks for sharing the info. I'll give it a try. We can use the extra thrust at this years Christmas parade. I forgot to mention that the trans ratio is 2.52. Mahalo ... Fred
