Scarab 1
 

I am doing an oil change/plugs and wires in a mercury 350 260hp V-8. Motor has around 400 hrs. on it. What is the best oil to use? S.A.E. 40 weight? And what oil filter?

Also the gas cap broke off and was wondering the best place to get one? Boat is 1985 Wellcraft Scarab1.

Thanks for your help!!!!!!!!

TTT

Someone here has got to know what weight oil to use!!!!!!!

Hey, I kinda liked the rag as a gas cap. :D

Straight 30 should be fine,
Usually, the recommended oil
is posted on the decal on the
flame arrestor/ plastic cover
( if applicable)

hope this helps,

I, as well as several others, run Mobil 1 synthetic in my 350 MAG.
In the summer I use 15-50 and 5-30 in fall/winter.

As for the gas cap, check out West Marine or Boaters World. They'll have what you're looking for.

Using a rag, eh? Hope no one smokes. :crazy: :crazy:

"good stuff" ;) :D

Thanks for the help!!!
I'm going to pick up the mobil 1 synthetic since it already has about 400hrs.

Rag........ what rag? ;) :D :D
