I think it needs to be a two part question. once you get your setup where you want it, prop, porp height, setback etc. maybe add some compression, you need to decide what you are willing to give up for the extra mph. more rpm, smaller, lighter flywheel, smaller alternator, so no more long idle times, re ring every 100 to 150 hrs, no oil injection, remove the floor from the boat, and everything else that is'nt bolted down, run a huge prop so one passenger max with you both leaning over the bow to get on plane. I think it depends on what you plan to use it for, as you can't have everything in one boat. having a ton of money sure helps though LOL! btw the no oil injection dous'nt apply to Yamaha LOL! the pot is stirred now!

Yep...got all dizzy and fell down.

It was suprisingly easy to add 11mph to my top speed actually....gotta love the internet. I think I feel 107 coming on...yep...just ran a 107.2 .

I figured you were doing at least 50 when you got out on to the lake from the launch so you could string it out.

I'm all out of money.... But all I need is to tie Dok. But I've got work to do.

Especially since I've got all these numbers on the keyboard here...I don't even need to get my boat out of storage to beat you lol.

That's it, I just put the call into the dream police to come check your dream meter then!

Around 1994ish Hot Knots had a "try a propeller program". I borrowed a 26 Hoss Hyperdrive and picked up 6 mph. Of course I had to buy it and of course it was stupid expensive. $900, the most I've ever spent on a prop.

Having said that, if there was a $900 prop that was 5 mph faster than my small ear chopper, I'd buy it. That would be 4.6 mph faster than my 31 Triton. I'm talking my gps, however inaccurate you want to believe it is, it is consistent.

I think I'd be more interested in spending money on acceleration.

iv been waiting for someone too stir tho pot on oil injection,,,i have it on my excel,,, my buddy has his deleted on his excel ..i think im fine (better off) with it,, he thinks pre mix is better,,,,

The yamaha oil injection is the best in the business...the only caution is that the excels are getting old...so...the oil lines are getting brittle and the check valves are getting sticky...and...the pump is getting old. It might be a good idea to check out the oiling system and make sure there's nothing glaring.

,, id be willing to put in some hours on setup testing ,over $$$ out of my pocket that could be spent on gas hauling ass either way.
