Re: g3 1652
I have a C1652V (crestliner,rated 60hp console,35 tiller);first couple years I used a 40hp(Suzuki DT),went around 32-33mph.Currently using an older 30hp(Mariner/Yamaha,1987),goes 28mph,both tillers.These speeds are by myself(175lbs) but with fishing gear,batteries,trolling motor etc.(approx.250lbs).
You will most likely go faster because the hull of my boat has a tunnel...I've read it hurts top end(approx. 3mph).
I like the 40hp...not just because of the 4-5 mph extra top end but the time it took to get there was pretty quick
Like others have said, a 20hp would do it but if you are going to be taking other people and carrying a load,your going to wish you had more.
I'm currently trying to buy a 25hp etec from a guy,I heard there a pretty strong outboard in the hp range and most(95%)of my fishing is done by myself.
