90HP Fuel tank

speterson1011 · Sep 23, 2010

What size tanks are most of you running with 90 horse power engines? I have a 2001 2 stroke 4 cyl. Johnson and only have a 20 gallon tank. It just seems like not enough to me so I figured I'd see what everyone else is running. Thanks

Re: 90HP Fuel tank

It depends on how you operate it. I do know, as you stated, that a 90 HP 2-stroke will make short work of 20 gallons (probably 18 usable).

Most of my boats, that I owned, typcically had, 30 gal. plus+.

Re: 90HP Fuel tank

Yah I usually carry an extra 6 gallons on board. I try to be gas efficient but sometimes I just want to get out there and go everywhere which is why I bring the extra 6 gallons. Just wish it was a bigger tank so I didn't need the extra jug but I don't have room. But then again it is a flats boat, not a cruising boat

Re: 90HP Fuel tank

dunno
I have an F150 yamaha and a small 65 gallon tank.
depends on how far and fast ya wish to go.
but that 90 2stroke can and will burn 10 gallons an hour with no problem.

Re: 90HP Fuel tank

15 gallons in my 14 foot go-fast. Two sixes in my 15 foot Glastron. That's her in the avatar.--not enough fuel, but I can't fit more. Anyway, it is used mostly on the river.

Re: 90HP Fuel tank

With my 90HP 2 stroke I have a 12 gallon and a couple of 6 gallon jerry cans. Everybody hates that queazy, "hope I have enough gas" feeling. It all depends on where you're going, how fast you're running and how far apart the gas/marinas are. At wide open my 90HP will really rip through a tank of gas, so I usually cruise in the 3500RPM range, which helps a good bit.

Re: 90HP Fuel tank

I have a 90HP 2stroke Merc, I have two 12 gallon tanks. When I take the kids tubing it will go through a tank pretty quick. If I go on an extended cruise, which I rarely do, I have a 5 gallon can that I fill up and put in the boat as a reserve.

I never go out without having both tanks full, and I really try to end the day with at least 4-5 gallons left. My tanks are the "portable" type, the hull does not have hull tanks, so anything bigger would take up too much room.

Re: 90HP Fuel tank

my 90 in my bass boat has 18 gal...at WOT it does about 42 so I can cover about 80 miles on a tank...

Re: 90HP Fuel tank

Yep I have burnt some gas up quick and made me wonder if I really had 20 gallons. Wish it was a 30 gallon but Oh well I can make it work and just be more gas efficient

Re: 90HP Fuel tank

I have a Yamaha 90 HP 4-stroke with twin 12 gallon tanks. That gives me a good 100+ nautical mile range dpending upon the weather and operating speed.

Re: 90HP Fuel tank

Hey everyone I just recently did a test with the 18' flats boat, with a 2 stroke 4 cyl 90HP Johnson. I use Quicksilver(mercury) premium plus 2 stroke oil. I filled up a full 20 gallons of my tank, carried a extra 6 gallon jug of gas with me. The water was absolutely flat when I was testing it here in Tampa Bay. I ended up doing a total of 75 miles according to Lowrance H20 GPS and I didn't run out of gas at all and didn't have to use my extra 6 gallon jug of gas either. Just thought I'd share, I was impressed with it. I was running about 23mph the whole time. I was pushing about 1900lbs. I just recently got my prop re-hubbed and re-conditioned and man did that make a difference! Thanks for the replies and information everyone
