2 tanks or 1 for 1984 Johnson 70 OB

[Straightup]

Really glad to be part of this site!<br /><br />I have a Jonson 70 OB on a Rinker V153. It has 2 above deck tanks right now that need replacing. I think I found a 12 gallon tank that fits under my ledge where the 2 tanks are now.<br /><br />Do you think I should stay with 2 tanks? I think it would be handier to only have 1 tank, but maybe sliding that big tank out to fill and slide back would be a pain. Also, I heard these engines are pretty thirsty. Do you think a full day of Skiing would take up more than 12 gals?<br /><br />Open to any suggestions / comments.<br /><br />Thanks<br /><br />Jeff

Actually, Jeff, that 70 is pretty fuel efficient as 70HP outboards go.<br /><br />Unless it causes you space problems I suggest that you stick with a pair of 6 gallon tanks. They are much easier to take away to fill at a gas station for a lot less than at the marina.<br /><br />You also gain the advantage of being able to empty one tank and know exactly how much you have left.<br /><br />Good luck.

Thanks JB. Cost wise, it is about a wash, so no big deal staying with 2 tanks. <br /><br />Nice avitar too!<br /><br />Jeff

"full day of skiing" ?<br /><br />12 gallons will probably last about 3 hours if run hard, 4 hours if you are taking it easy.<br /><br />Keep the old tanks around as spares.

I have a 70hp 'rude, 12 gallons should get you through the day. I use a pair of 6gal because I don't want to lift 75lbs of gas tank into the boat. You do put the tanks on the ground (or the dock) while you're pumping gas, don't you?
