Spark plug gap? And how the ?!@@# do I get 'em out?

I have an '89 Tristar 190, Ford, Indmar. What is the gap on the plugs, and how in the world do I get them out? There seems to be no room. Thanks.

Oops. It's a 351.

New here too, but I enjoy this board. Anyway you might try a spark plug socket with a wobble. As far as gap, call the dealer, they'll tell you.

Gap should be about .035" and you can use a box wrench. It's not limited to the length of the socket that way.

.035 on my 93 351HO. Aren't Ford's fun. Chevy's are much easier from the looks of it.

To me, this forum is about love of inboard boats. It is about the sharing of information and, on a good day, some humor. It is not about post count, brand of boat, or any other superfluous labels that lend themselves to a false sense of superiority. Please, respect one another, try to pass on accurate information, and keep your eye on the ball.

Are the plugs really that hard to get out of the 351? I have a 351 in my 1992 Ford Bronco and although the right rear plugs are a pain, it's because I can't get my hand and socket in the right location easily because of the A/C unit. With a boat I'd think it'd be easy. What's in the way, the exhaust manifolds?

Easy & inexpensive...buy a Craftsman spark plug socket, they have a 5/8 wrench flat on the end, use a wrench to turn the socket. No broken plugs and takes care of clearance issues. .035 is the gap.

Scott, I had the same problem on my Bronco. PITA. Not looking forward to doing it again.

Remember the Chevy Monza? You had to lift the engine to change the spark plugs!

.035 on gap. I was able to use a spark plug socket on 2 of them and the rest I just used a box wrench. It is actually pretty easy.
