Well I talked to Mr. Whipple himself because I have a 525 efi and I am looking for options to get around 750 HP for my boat. I asked him about the heating issue and he said it isn't a problem with the whipple install. I had called a vortech dealer and the vortech factory said they wouldn't recommend using their product on 525's because of the closed cooling.

I have to admit, in the past I have always thought the procharger technology made better sense because it is easier on your drives, but after looking at pics of the whipple symstem on a 525 I don't know how anyone could come up with a better looking package. Man that is beautiful. It's looks like something stock from the Merc factory.

Does anyone have any feedback on whipple/525 efi install? Did they go with a bigger heat exchanger?

I'm looking for opinions here, I have a set of brand new 525 efi's but want to put 700 - 750 HP in my boat. Would you whipple them or just have a set of engines built for that purpose? One thing I do know is that I dont want to have to adjust valves so I"m going with hydraulic lifters.

The ones I am hearing about with the factory ECM on the 525's are having problems.

Hey Strip:

I haven't contacted anyone yet..just gathering information and waiting for my warranty to expire. However, from what I'm hearing, it seems as though there are some major changes to the engine. being a greenhorn about all this stuff makes we want to wait until they have things perfected.

For now, I'm going to play with a few props to get optimum performance on the stock engine. However, my Pantera with the 525 needs more power to get it up around the 80 mark. I feel the boat runs the best in the high 70's low 80's.

Thanks for all the information.

Thanks Monstaaa

Any time you make more HP you build more heat. If you do install a supercharger and you have trouble with the motor running hot, just have to buy a big HP closed cooling unit used on innovation motors that will fit in the same location and are priced very reasonable. Roughly $1000 new. I wouldn't let the overheating issue be a factor with your supercharger decision.

FT, Sorry to ask again but what r u seeing for speeds now with stock 525 and what prop? Thanks

monstaaa

absolutely, you replace the entire management system as a whole. The new unit is a complete package from fuel system to ignition system , etc,,,,,,. evidently mercury has of yet not released the rights to mess with or improve the 525 ecu to the after market world. how ever keep watch 525 guys for theres a couple of companys that sprung some big woo for those rite's.hhhhmmmmmmm hhhmmmmmmmmm, arizona is one.
