Fella on another forum asking if this cam is good for a boat.

Need more info than just ‘a boat.”
You know the drill ie: info needed to help pick a cam

1989 Rinker 21 foot something

One of those Pro mechanics says this is what he needs. For me it looks like a car race cam and not a low end torque truck cam, hence the question

Not a race cam, but yeh, prob more than he wants duration wise.

so, other questions would be:
exhaust ?
compression ?
heads ?
intake
carb
needs/wants/type of use

The two most popular cans on a 350 merc is
1)comp cans 212, 218 at .050” / 112lsa
and 2)comp cams 218/224 at .050” 112lsa

1st: factory exhaust, normal runavout boat, 8:1 to 9:1 compression

2nd cam : aftermarket exhaust, performance type boat, 8.5:1-9.5:1 compression

This is the thread, maybe you can obtain needed info

The pics are blurry, even the pics of documents. Says I must join. I don’t want to. He can post here if he needs or wants more info. Tons of marine sbc guys here. Stock and performance.

I’m sure most of us would be happy to help.

Speaking of which, there is a lot in my short post above. Lol.

Not letting me send you guys any replies......
 

Saying I can’t put in a url, but I am not trying to put in a url..... confused because I’m trying to give you guys all of my information!

Hoping this will finally post...
 

Owner of the boat specified!Started with a “floor patch”.. then found a jb welded block.. pulled engine and bought a new one. Engine builder I got it from said the cam would be fine for a boat

Not letting me post... saying I can’t add urls until 10 posts
 

I’m not adding any urls.. so frustrating

1989 Rinker Captiva: not letting me post pics....
 

Not sure I can help myself here... can’t post pics and this is all super frustrating. Have tried posting over 20 times
