Anyone know of any tips to squeeze out a little more power?
Exhaust mods?
Intake / Airbox?
Does this motor have reeds?

Any other preventive maintenance tips on this motor?

The only mods I have know of are impellers. Both Solas and Mercury make an impeller to give you a bit better hole shot and acceleration, but you will lose a few mph on the top end.

There are reeds, but I have never searched to see if any of the companies like Boyesen (sp) make a performance set. If they do I imagine they will be fairly expensive as there are six sets.

They have them for various Mercury engines, and doing so gives you control over engine parameters so you can optimize for economy, power, speed, etc.

Not inexpensive, but if you're serious this is how to get "control" over your engine!

Looks like it would have been the ideal tuner....
Not available for Optimax. Damn.

These work awesome on other applications,
Put somthing similar on F350 Diesel dually, really woke it up!
