LS Swap Seafari 25

EDIT: a plate to plate will not work. Much, much more cooling required. Do NOT attempt


It has occurred to me that I made an error in telling you it will only be 350k btu’s. That’s the main heat exchanger however there will be additional 50k (25k for power steering and oil each). So I’ll try to figure out what that looks like.

Heat soak is also a concern. I plan to have a bilge vent blower on the bilge exhaust side keyed to ignition so it pulls hot air out of the compartment and should draw cooler air in naturally. This blower is not to be confused with another blower I will install for venting gas fumes.

Thanks for doing all this math. There really is only one way to find out for sure. It will have a ps cooler and an oil cooler.

If needed a bigger exchanger is not the end of the world. But we will see. I’ll get up on plane and get going fast on rare occasions but majority is high speed trolling. 13mph. Give or take conditions.
