new 50hp..

Last one I had in 2006 I had a brand new Tohatsu 50hp and only ever managed 31 knots.. I don't know if it was becasue the engine was barnad new, but one up was 31 knots 2 up 30 knots.

My older versions with a Clamshell Mariner 60 got 37knots.. so was disappointed with the Tohatsu.

The 3 cylinder yamaha 40hp seems the best as is much lighter than the 50, but is bigger than the 30hp. Very responsive engine.

4m searider is not being driven properly unless you are chine hoping with a big grin on your face!

Can't get mine to chine walk, even if its trimmed all the way out with the 55 on, still get the big grin factor though!

update on speed

tried the 4.0 with my SS prop. It is about a 16 pitch with what I am told is an sagressive cup. After a few runs I got great acceleration, at about 39mph it started to porpous, , The motor has the newer dolphine one piece wing, Playing with the trim I got to 42 mph and was running at 5500 rpm, max rpms for the motor. I decided to take the fin off the motor and ran the boat a couple more times. the bow lift without the tab is always fun. My experience with the natilus trim tabs on my 5.4 and the fin on the 4.0 work wonders to put the boats on plain. great for heavy loads Im sure. I achieved speeds of 41 1nd mayby 42, I still have to check the gps. Without the fins though I did think the boat started to get a lot more looses a few mph than with it, I would porpose not bad and I could slow it down a bit by trimming the motor but it never went away. My concern now is that I had a lot of water being sprayed straight up at my motor from the starbord rear tube. none from the port side. the water was like a hose turned lose. I have a small seam lose and didnt want to continue playing with the possibility of it getting worse. hope this is usefull for someone, And I will post some pics soon.

I have no real experience with the force engines personally. I know they are an offcast of all of the old chrysler (not a spelling test ) engine parts with a mercury marine badge on it. I dont think I would haave one
