I have a 27 fever with a 502 that I'm putting a Whipple on this winter. Looking for 650-700ish hp.The drive is a stock bravo and I'm sure that going to be the next thing I need, wondering what drive I should buy or upgrades to the stock one. Thinking -2 lower too?

An Imco SC upper and lower should be great. Get the lower blueprinted. Hering props.

Should I go with the in imco -2 lower

I have a imco lower -2 . Ran for a couple hours. $2500 firm

Good advice so far, the IMCO SC lower is sexy and fast, but plan on still rebuilding/freshening your drive periodically since most these bravo based drives still share many internals with them like gears etc.

Another option is buy a matching stock drive and when it breaks swap on the spare and send the broken one in for repair, or just freshen ahead of time before it breaks.

No matter what bravo based option you choose you will end up with the bravo blues

Any other non bravo gear drive options will cost a ton of money and speed lose.......

Mr. Gadgets Dick Tryce, All American Drive Service, The Bravo Shop, Max Machine Works all specialize in upgrading bravo based drives.

Well I'm not going to want anything, that makes it slower haha. What would make it faster

Not a Better Drive

We couldn't keep a Bravo style drive alive for a single season behind an 800SC Eddie Young motor in a 26 ft AO. Keeping a spare drive around makes sense but for us the drive would always go at the worst times. Two years in a row the drive failure disrupted our family vacation. The first failure happened the week before our annual trip and second a year later the second day of our week in Cumberland, frustrating! Then we installed IMCO SCX upper/SC lower and had a trouble free boating season. You may want to look into a more expensive upper (IMCO SCX or BMAX) the first time around. I'll bet some cash you'll save money on your drive budget if you keep the boat for a few years.

Was just gonna say I've seen scx uppers hold up well. Scx upper and sc lower seems like a good option to not negate speed and stay together.

no doubt , like the last two members say imco scx upper and the sc lower all bravo upgrades to let it last will be a waste of money as it still blow and ruin your day or days of boating .
