oil tank placement
 

right now I premix the oil in the fuel tank as the oil pump dosent work. were the oil tank was I built a small bait tank under the stern hatch,

the floor bait tank id like to seal off and install a water tight hatch lid. if I ever install a new motor id like to install the oil tank in the old bait tank under the floor ,. is there any reason this wouldn't work?being too low?

they are usually 3 gal, not sure its big enough, on my MA its on the old battery platform in the port transom but I have more room back there I know.

the tank I removed I still have and fit in that 9" or so wide hatch it will fit below im sure as I measured it before when I was thiking of it . it not 3 gall maybe 1 I did remove some oil from it about a gallon id use it if I could im just wondering it there a high issue for getting the oil up to the motor id think it would pump up ok

stay with the pre mix cant go wrong that way works great for me no more smokin

The oil take for my contender is in the bilge area and has been fine.
Definitely lower than the engine.

The Yamaha tanks have a carbon steel "mount" that rusts easily. There are SS available though. They also have a small, inline filter close to the bottom that's easy to change but needs to be accessible. I had one clog once and manually refilled the engine tank to get home :(

Where do you get the stainless oil tank mount? The one in the bilge my 23 contender is rusting. Also ive never seen the oil tank filter. Where is it?

My merc 150 is spec'd with 1.5 gallon tank and works perfectly. It's a positive pressure system,height is irrelevant.

Yamaha #646-24251-02-00 strainer. #21 You'll have to search THT for the SS tank strap. Yamaha wants $150 for theirs.

I found a place that makes the stainless tank mount for 119. How often should that oil tank filter be changed?
