Post REplacing my 27 hp power head with something bigger
OK I have a 1754 g3 with a 27 hp kohler its a pro-drive with 130 hr on it and I need a lot more power. just me in the boat it does fine. I have not gps it but I think im doing around 25 mph but when I put any weight in the boat it falls on its face just with one guy and a dog and decoy it will olny do like 10 to 13 mph if that and I can forget a third guy I live in northern cali. I run the delta,rivers and klamath falls. so I dont see alot of mud but I run in 5 to 12 inches of water but a of hydrilla weeds so I was thinking of putting a new 40hp kohler on it what do u guys think would be best

Ditch that G3 and buy a 1748 or 1848 Pro-Drive boat or something similar and then see if you still want a new powerhead.

Your not gonna get the full potential out of your motor until you buy a hull that is built for a surface drive, and a G3 is not. Nothing against G3, I own one, its just not made for a mud motor.

Bolts up with different spacers from Prodrive, there are aftermarket parts and it will put up good speeds. Better built block, cheaper than the rest and a torque monster out of the hole and mid range.

The evt exhaust would fit with minor modification. I think Bfenn gutted his stock one. Don't know what you would do for a new custom one until EVT gets a new builder for theirs though. My machine shop guy said he could build one, but he'd need the whole motor. Also a random machine shop guy probably isn't going to understand the need for bracing which we all know it's pretty damn important to get the bracing right.

I had a new stainless exhaust built, Chops welded it up and got the parts from EVT. Carb is a must and a fuel pump!!!! You can get aftermarket parts from EVT, flat top pistons, cam and he can modd your stock heads. :mrgreen:

I bet you could buy this one http://cgi.ebay.com/Generac-44hp-Engine ... 2c5b51f58b Throw a carb, exhaust, and fuel pump on it and be ready to roll. Although I'm not sure if you would need anything wiring wise.

I been talking to the guy on ebay. They are working on selling one with a mikuni already on it. Don't think they are gonna re-open shop until the end of march or early april though and they'll have to build your motor after that.

He is a great guy and very knowledgable, he did call me and asked about the mikuni and I gave him EVT's number maybe they are doing some business together
