Converting a Carb 787 Engine to Fuel Injection

[frank.dimambro]

Has anyone ever tried to convert a 787 Carb Engine to Fuel Injection.

done a decade ago, problem is, on flat water, it screamed, its when it porpoises, the ski "loads" up.

what about a boat, which shouldnt porpoise?

just curious...

I've no idea what 'to porpoise' means, I'm new to owning a Seadoo. I was asking about the conversion because I would like to know what it would to do it, is a kit available???. The Lake where I would like to take the boat has 2008 EPA rules applied, so Sea Doo Challenger with it s CARB engine is not allowed any more. But if I can get it running on a Fuel
Injected system I think I could fix any emission problem. I'm thinking replacing the Carb with Fuel Injection would be easier than replacing the complete engine.

porpoise is when your ski is at speed, and it starts to jump out of the water a little bit, dive back down, jump back up, dive back down, etc.... like how a dolphin or porpoise jumps out of the ocean

i dont have a ski, but my uncle's 1990 ish yamaha does thisif you dont lean forward... it doesnt have any kind of trim system
