That sounds like a good setup. Are your scuppers completely submerged when the boat was docked?

Not now, 2-1/2" above waterline. Before the diet, the bottom of the scuppers was at water level.

Just giving everyone an update. I had pretty much made my mind up I was going with a 140 Suzuki. Went to the local dealer and was not really impressed with them. Didn’t want to be tied to them if I ever needed any warranty work. So long story short, I ended up working a deal on a new mercury 115 pro xs with command thrust lower unit. I really like the dealer I got in touch with and feel like this will be a great motor for the 18. It’s about 363 lbs so almost identical weight to the 130 2 stroke I removed. And with the command thrust lower unit I’ve got plenty of prop choices so I should be able to get it dialed in perfect. I appreciate everyone’s help and I’ll be sure to post up the performance of the new motor along with pictures after I get it installed.

Good Luck with the new motor. It is soooo important to get a good feeling from the dealer who will service the motor later...sounds like you made the right choice.

I have the Yam 70 4S on a 17' War Eagle and absolutely love it! That said, I wouldn't want it on a 18' SeaCraft.

Well done Mr. Bandit!!!! :)

Nice!!! Please post some numbers after you get a chance to run it a while.

What size propeller are you running with 90 HP and 115 HP ?

Not sure about the 90s but I know with the 115 command thrust motors a lot of guys are running 14.25 x 21 pitch props on similar sized boats. So I’m going to start with that and see how it does.

How much did the ride and min plane speed improve?
