21' Pulsar 250XS
Was told to put a 23 prop on it to stop the chinning. Now I only get 66mph out of it. Have a jack plate set back 6" and have the engine mounted as high as I can get it. Want more speed but don't want to flip this baby trying. I am told I should be getting at least 75mph out this engine/boat. 2009 Pulsar B/R with 2006 factory rebuild optimax 88 hours. Can anyone help with this?

Current setup with not even close to being tuned properly and not at all broken in 200 Mercury and 1.87 lower spinning a 25 pitch Laser II . No jackplate sitting way too low on 2nd hole down . 71 MPH GPS at 6100. Installing jackplate over the winter along with hydraulic steering. Shooting for comfortable mid 70's and 80 MPH top speed.
Is that a 90hp opti? Or a 300? On a 16ft boat? Or a 26 ft? Something tells me we need to know....

Seems so. Good to see it pushing another 'mate.
Ive got a 225 Pro Max injection set to install. We'll see how it runs with that. Almost a shame though. It runs pretty good with the WMV carbs.

That was bumping into the 7200 rev limiter. Probably go faster with more prop. I think I'm good at this point 
I'm running about 155 lbs compression with that motor. I like to mix 92 octane with 25% AVGAS to yield 95 octane. Its cheap enough but hard to get as the local airport is locked up to non plane owners. I have a friend who is a pilot and I asked him to pick me up 20 gallons of AVGAS which probably would last me most of the season. He asked what I wanted it in and told him gas cans would be fine. He asked if he could just get it in a drum and said that was OK. Apparently to him that meant a 55 gallon drum...full. So I spent the better part of Saturday afternoon siphoning fuel into gas cans to get enough fuel out of that drum to be able to get it out of the back of my truck.
