Suzuki DT150 Gas Gulper

[vinnyp]

My first post here, so here goes.<br />Have a Suzuki DT150 EFI on an Angler 204 fiberglass hull. On recent trip, using GPS, clocked the engine running 1hr 57min and traveling 34.73 miles. I had 3 men (approx 550 lbs), 20 gal live bait well full, 40 lbs ice and a full tank of fuel (80 gal). Ran engine 3500 to 4500 rpms. I used the trim tabs to adjust the maximum speed at current rpm to get the greatest fuel efficientcy. But to my dismay when I returned inland and refueled I had burned 23.5 gal of fuel. This is almost 12 GPH which seems a bit much I think. Engine starts fine and seems to run okay except for the excessive fuel burning. Any suggestion here would be greatly appreciated. Thanks

vjportera: With carrying about 1230# load in the boat and running 4000+ rpm 12 gph isn't bad. At WOT you will probably burn 15+ gph. With 80 gal. fuel at 12gph you've got 6+ hours of running at that speed. Sounds good??? 150's burn a little more than 50's.

I have always heard the the Suzi likes gas. My friend ran a Suzi Special edition 200 and while I got 12 on my mercury 200, he would burn 14-15 gph on the same trip. <br />Sounds normal to me also.

Actually, sounds like your fuel consumption for the load you are pushing is right on the money.

If unhappy trade it for a DF140 and get 6-8 GPH at those speeds.

Thanks guys,<br />I guess i will just need to fill my pockets BEFORE I fill the tank. <br />Would I expect the same performance from a 4 stroke, and if the boat tag says max 185hp could I push to 200hp.

4-stroke will give better fuel economy, but don't exceed the boat's rating!<br /><br />Good luck!
