Well, I guess maybe I need to start checking this thing over a bit more. Timing, no idea; fuel mix - too rich, I know there is more on the table. http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/smile.gif

Lookey what I found tonight...I think this might be worth something. http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/smile.gif

Pretty sure at WOT, the butterflies are supposed to be all the way open. http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/smile.gif

I had an old Merc Tower of Power 6 cylinder. If I remember right it had 3 2 barrel carbs. Each barrell had its own jetting screws. It was a pain to adjust the butterflys, really a pain when you broke out the vacuum gauges. Man, you are gonna have some fun. But always good in the quest of speed!!

That looks like a nightmare.

It wouldn't be worth doing if it wasn't fun!

Speaking of the Tower of Power motors, ya know the nastiest one Merc ever built was called the T2x. 99 cubic inch inline 6, ~200 prop HP. Full factory race motor.

My dad has 3 for his project Allison boat. http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/smile.gif

If it is any help Keith, I have the factory manual. Just let me know if you need any numbers from a "stocker".. It looks like a ton of fun, picture 24 carbs WOT on the back of mine.. can't wait!

I think they are suppose to be a little on the closed side. Might want to check the manual for throttle positioning opening. I saw this many times as a certified outboard mech and said wow I can get more out of it but ended up going back to factory specs as the motor/s had a serious BOG and was lagging power. Its been a while and I might be wrong. then again on the 225 johnsons I had they only ran 6000 and after throttle adj I got 6200 out of them. I also gave the motor cover a vent http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/smile.gif (more air)
