So I just bought my first "real" boat, a 1860 G3 with a 50 yamaha 4stroke with a prop. I know this is a bit heavier boat but I'd like to put a jet on it at some point. Good idea or will it be a dog and under powered?

Not sure to validity of it, but I heard a rumor that the 50 horse 4-stroke could be hopped up to similar HP as the 65 Yami. Again, not sure about it, but it might be worth an inquiry if you're looking to swap over to a jet.~Alaska born and raised~ •'04 Duckworth, 5.7 w/ 3-stg. •High side Lowe, '13 Yami 25 prop+Merc 40/30 jet

I've got the same G3 w/a 50hp yami. When i got it the engine had been detuned for the 35hp kenai restriction, it went ok with 2 guys in it, the previous owner had given me the original 50hp brain box that came with the motor so i asked at Deweys what it took to change the motor back to a 50. Well they told me it was a "big job" very involved and expensive so i said never mind and went home. That winter i did some research and it turned out all i had to do was swap brain boxes, plug & play and readjust the linkage a bit, total time maybe 1 hour and i didn't know what i was doing !! so so much for the "big job". Next year i bought a jet pump from Gary at Greatland Welding(great price) for the boat and installed that myself also in about 2 hours & boat runs great with 2 guys and some fishing gear in it but not as fast as the 50hp rating with the prop. I've heard there is a restricter in the carb that if removed will give you 60hp and i'd bet it is a easy mod to do, might have seen it on youtube or just googled it. Boat would be a lot faster if it didn't have all the extra trim and seats in it.
