johnson gt 200 hop up

[durandbagwell86]

I have a 86 johnson gt 200 and wanting to make more power out of it. It's the 2.7L, so far I have only drilled exhaust and opened vents and flipped them around on the cowl for more air, I have it down now putting new stator on and fiber reeds. While I'm at it I want to work reed cages and shave heads but know how much I need to cut and what a safe compression ratio is on 93 octane, right now my comp. is 100 lbs on all cylinders. If any one knows any other hop ups or tricks with exhaust tuner, intake manifold, or carbs just let me know, I already know I'll have to fatten up on the jets. Any help at all will be great, just dont say get 280 merc. I've had the motor for a long time on my old procraft and love it, just want a little extra. It's on a light hull, 600lb allison 17ft xst bass boat. You guys are great and thanks for the help so far.

When you get done with all the motor work, get ready to spend another couple grand on the lower to get it to hold up when you run it high on the plate like the allison's like.:)
