Better compare the gear ratios of your motor and his! Just because the HP is the same doesn't mean they'll want to turn the same rpm or same prop!

Will do. I'm gonna stop by my local yamaha guy and see if he will work with me to make sure I get the right prop.

Got the interior faired and primed. Ended up sanding through in quite a few places. I would like to paint over it but thinking its gonna need another coat. It looks pretty darn good and I would like to avoid spraying more primer but I will I'd it's necessary. I've done some research and have seen some info saying to sand with 320. The awlgrip guide says 220???

I like to do my final sand with 320 and even 500 sometimes prior to paint. 220 just leaves to much scratches. It works well for knocking down thick high build but I would shoot one more coat and lightly sand with 320 to keep from breaking threw. If you paint over that it will take may coats to hide the white spots. Grey and white are good to alternate as you can see where you do sand threw and makes it easier to see where you applied it at when coating but it will bleed threw if you paint on it like it is in the final picture. The base color makes a big difference in the look of the final coat. Also I like to prime with a high build primer or a base primer. Your last coat should be done with a sealing primer or final primer prior to paint. Big difference in the two types of primer. The final pre paint primer will not sand well but you shouldn't need much sanding on it. I usually wet sand the last coat of sealing primer. Make sure you don't break threw down to the base primer or you will need a recoat. You can paint over what you got here but for the best finish add a few coats of final prep primer prior to your paint work. This is how I do it any way, others may have different ideas.

Thanks for the advice! Finally got her painted and the nonskid down. Awlgrip with rhino hide additive for the nonskid came out great! Also dropped the boat off last night with Don at Hermco. Really glad I decided to go with one of his brackets cause they are nice! Ended up going with the 24" setback.

looking great!

Well got her in the water and couldn't be more pleased! Top speed 52mph at 5600rpm. Could use a bigger prop fir more speed but its perfect for how I load the boat. The motor is mounted three holes down which seems to be the best performance. Slight porpoising when the motor is trimmed up at lower speeds. Tabs or trimming the motor down stops the porpoising. Couldn't be happier with the overall finished product. Thanks to all for all the help and special thanks to Deny for all the technical insight!
