Default G3 1652 SC with a Yamaha 50 4stroke

Hello THT, I was wondering how fast my 2009 G3 1652 SC with a 2010 Yamaha 50hp 4 stroke should go. it has a hydrofoil and a standard 3 blade aluminum prop. Im getting close to 38mph

Don't know what a G3 1652 SC is, don't know what RPM your motor reaches at WOT, so maybe that speed is fine.

I had a similar set up on my jon boat and got about 10 mph faster. It was a 1652 Sea Ark with same power.

I don't know the boat either but just googled it - I would say 38mph is good going on a boat that size with 50hp - but if you're running an aluminium prop, there is a probably a little more to be gained, but to get the wisdom of those in the know, you would need to advise your current WOT rpm, how high the engine is mounted etc.

1652 means 16ft long and 52 wide at the bottom. i would say 38 with a 50 is pretty good!

I think you're running nice personally, wouldn't expect much more.

I have a buddy that used to have a 1652 G3 with a 70 on it. I don't recall what his top end was but I do vividly recall the hull got real squirrelly before you could even get to WOT. If I were you, I wouldn't be looking to go any faster than 38.
