I have a 2002 1756 G3 Center Console (the regular one NOT the Jet tunnel model) with a 40 hp prop Yamaha. Jumps on plane in 1 boat length and runs WOT at 31mph on GPS, and can run on plane at 15mph, it can run on plane in about 18 inches of water.... I would like to do a re-power while the current motor is still in good enough shape to sell and make a little $$$ off of. I do want to put a jet on it regardless of what the people around here say about it. Its rated for up to a 70hp. SusqyG3 has the same boat with a 90/65 jet which is still within the rated HP for the boat and would be more than enough HP for me. BUT!
My question is when I see boats like the blazers and allwelds with 150's and 250's on them I get to thinking... Why can't I go bigger? I looked at the Alweld 1756 JC (basic jet boat) its just a bare bones hull the same size as mine and its rated for 130hp?
Nevermind what the rating is for the boat or if its legal or not.... I am seriously thinking of putting a 115/80 Yamaha fourstroke Jet on my G3. the weight difference between the 90 and the 115 is only 11lbs and it's a 15hp gain.
If I do this I would be replacing the current factory center console with a fwd setup like the factory G3 jets come with and mounting both batteries under the console to offset the weight a little. that would leave only my fuel in the back. I currently run one 6gal tank and one 3gal tank. Without the batteries back there I could run two six gallon tanks (a 12 won't fit its too tall). I figure that either the 115hp or the 90hp fourstroke would get similar range and fuel consumption to my 40hp 2 stroke.
I would also be adding a jackplate to get the height set right.
Since no one on the east side of FL has a jet outboard I need help and suggestions from you guys here at tinboats. I really don't need the jet here in Northeast FL but the Gulf side and some of the rivers in central FL and southeast Ga are pretty shallow. Every time I have to slow down and trim the prop up in less than 1.5 feet of water I know I should have got a jet.
SusqyG3 please weigh in on this since you have the same rig. Since no one on the east side of FL has a jet outboard I need help and suggestions from you guys here at tinboats.
