502 Whipple engine. Fresh water only. Merc 502 Mag Gen VI engine with Whipple top mount supercharger. CMI headers, Merc Racing valve covers, Scorpion roller rockers. Very well maintained with over 400 turn-key hours. *It's due for a re-fresh* Engine is out of boat and can be run on the stand for interested buyer. $8900

How long has the whipple been on of those 400 hours?

What kind of power does that package put out?

I don't know for sure, but I think the engine has a total of around 800 hours. It was freshly rebuilt when I installed the Whipple. So, it's 400 hours on the Whipple. It's 550 HP. I see you are in McHenry. The engine is in Ingleside, if you'd like to see it.

Is this complete. Fuel system, harness, assesories, ecu, etc.

Thanks

Yes I'm just down the road

I saw your boat at this years river shiver...looked and sounded great!

Yes, this is Everything! I replaced this motor with the Merc Racing 525 tweaked to 600HP. Just as a comparison, the Whipple motor pulled harder than the 525. But I did gain some speed with the 525.

When you put the whipple on did you do any mods to the engine besides the rockers?
Heads?
Cam?
Lower end?

Why is it due for a refresh? What is the issue? or is it just based on the hours?

thanks

It's a stock 502 Mag, stock heads, stock cam, JE pistons, and the already mentioned scorpion roller rockers. Because of the 400 hours I would want a refresh before going another season. I wouldn't feel comfortable sleeping at night without full disclosure.

What about the tails? Those too?

what size is the whipple?im in illinois and am interested.

Yes, tails included.
