thanks in advance,

here are all the numbers i can find on the engine.

carbs wh22-1
just below flywheel on the left(from back of motor)OB34218000
on engine mount ob314218
leg 1590-8334
i have a feeling it might be 220 v6

Just off the top it sounds like an older (around 83) 225 merc v6.

Check on top of the block above the exhaust chest, and on the left side at the bottom where the block meets the front half.
On the clamp bracket on the left side as well.
