Thread: RFI to carb?

    RFI to carb?

    Can you convert a 787 RFI engine to carb? Pretty sure the answer is no but I want to be sure.

    i asked this myself awhile back.you would need new jugs, pistons, fuel baffle, intake manifold, carbs, electronics, and head. youd be better off just buying a carbed boat.

    Not the boat I bought. Got a 787 RFI with a ton of extras for $100

    I have a related question. Can I use the lower engine cases from a 787 RFI engine with the rest of the engine parts from a '97 XP 787 engine?

    No cylinders crank pistons even the cases are different where the intake ports are so stay with the rfi.

    Yes you can use the RFI cases with a carbed crank & clys,etc.

    The RFI cases have a case cooler & works good to keep the cases cooler.

    Water Worx, are you 100% certain the RFI cases will work? I have all the other parts to rebuild an engine for a '97 XP (787) engine, so I'm looking at replacement cases on eBay. Is the case cooler oil or water cooled? Will it be easy to add that/hook up the case cooler to my otherwise stock '97 XP 787?

    the case cooler is water cooled. i am pretty sure that there is no spot on carb cases to bolt it to. but don't quote me on that.

    I'm not looking to add just the case COOLER to non RFI cases. Aren't they PART of the cases? I'm interested in using RFI cases (just the lower case) with all the parts (crankshaft, counter balance, top end, etc.) from a standard '97 XP engine
