trying to identify the engine

trying to identify the 6 cylinder overhead valve engine in my 1961, compact skier,(i think that is the model)...any ideas?

d*ck,
It's most likely a 170 Ford marinized by Interceptor but we sure need more information.

Welcome to CCfan. Besides pictures of the engine, we'd love some of the Compact too. Tell us more!

d*ck,
It is a 170 Interceptor. Regarding the prop, we have several members running the engine so be patient and they will chime in. Off hand, it will be a 12" diameter and I'd say 12 or 13 pitch. how's it run? What WOT (wide open throttle) RPM are you getting and what is the diameter and pitch of the prop now?

Nice Compact!!

d*ck,
If you don't have a engine manual, check out Marine Engine . com They don't list the straight 6 with a "add to cart" so if you do need the manual, give them a call.

d*ck,
I just checked and Bruce is correct that the manual is in the reference section. The 144 and 170 are in the same manual as the Y blocks.

Thanks Bruce.

d*ck,
Take a look at this thread before swapping props.

Did the restorer put the 13" prop on the boat?

If it's a 170, redline is 4400.

hi pete,
had to explore the site to find your name.
in response to your last post about the prop size.. they actually told me that it wasn't right when they installed it, but i had to try it out to be convinced.
so now with the correct size prop i put it back in the water to find out there is a new problem. it's not getting cooling water to the manifold. it over heated, pegging out the temp gauge before i noticed it, as the exhaust exits under water and one can't tell if there is water in the exhaust gasses or if it's just bubbling hot air. so i pulled it out of the water and put a flushing plunger on the water intake with the garden hose attached and still no water in the exhaust. so i pulled the hose from the downstream side of the impeller where it enters the exhaust manifold, there is water there and water pours back from the exhaust manifold when i removed the hose...??? seems there is something preventing the water from circulating in the water jacket.. any ideas?

d*ck,
Since the first test run when I'm assuming there wasn't a overheat problem and now when you do have the overheat problem, has the engine been run without water? The RWP (raw water pump) is a rubber flex impeller pump that's water lubricated. When run even briefly without water, the impellers can get chewed up. Check out the impeller. Also, I know the T stats for that engine are real fussy. I'd install a new one.

d*ck,
Maybe Steve (62wood) will catch this thread and comment on the T stat. I know he fought the stat problem on his 170 even going through several different stats before solving his overheat. I don't remember what stat he ended up with. I'll PM him asking him to comment.
