I would suggest Kreen before Seafoam.

Marvel's Mystery Oil works real good for slowly dissolving engine crud. Keep checking your oil and change it when it gets disgusting.
Berryman's Chemtool is a great engine flush. 1 1/2oz per quart of motor oil, add to a cold engine, idle it for 10-15 minute (maybe high idle, 1,500rpm), then drain.
Kreen's pretty awesome, too.
Keep the SeaFoam in your boat's gas tank, where it belongs.

Bad idea
What makes you think your engine needs to be "cleaned"
If engine is maintained.....no need
If it hasnt been....juju isnt going to fix it, and has higher likelyhood of causing harm.
I have seen valve stem seals immediately begin leaking and begin burning oil after using solvents to try and clean engines after prolonged negligence. Basically you dissolve the crud that was helping to seal the valve stems
Seafoam Works to remove carbon from cylinders introduce it in through a vac into manifold . I've done this on numerous engines especially 2 stroke Outboards over the years. It will free up stuck ring and increase compression on heavily carboned outboards. It will lower compression on cylinders that have carbon build-up that's causing pre ignition usually that cylinders been burning oil to build that carbon up. I've never had it increase compression on an automotive engine after decarbing. At least since the 1980s automobile engines are much cleaner than the old up 2 stroke Outboards were
I wouldn't add it to the oil though. And there's better things to add to the gas tank for cleaning injectors like Techron.
