I have a SR6 with a 1983 150hp Evinrude, standard (24in) shaft with a 12inch setback plate, compression runnig about 110psi. Empty the boat does have a tendency to porpoise. This was somewhat reduced when we carry our dive gear, it is all placed in the bow. I also noticed a 5mph increase with the addition of the dolphin and the porpoising also seemed to diminish. Top speed loaded 45mph at 4k RPM WOT.

On another note I have found an 2001 Evinrude 150hp Ficht that I was considering purchasing. Am I hearing that I should pass it over?

Jeff

t b.thanks 4 t input.whats t 12 inch plate you have. a word on t ficht, is k i s s. as in keep it simple st---d. these do not work. i live in a small area a friend got one of these against my advice. it was a 225, 50 hours on a set of plugs, he only used it himself and it was looked after , it still blew up , 2 pistons 1 liner all 4 no reason. he has since bought a 98 200 merc 4 1800 euro, and is delighted , well at least it runs and cheap 2 buy. if you want comfort either a suzi or a yam 4 stroke or stick 2 what you have if its running, may be sore on fuel but they are a tuff engine. no ficht or e tec all i hear are horror stories. keep in touch.

I dont know if this would make any difference but i was told that due to the transome angle being more verticle than some boats it stops the outboard from being able to have the desired trim effect and years ago it was common practise to have a tramsome plate wedge shaped to kick the prop end in further.It was an old seadog who use to test trail ribs told me

Went home and removed my trim stop rod to see if that extra inch may make a difference next time out. It was in the last set of holes closest to the transom.

Anyone have an opinion if this is a good idea or not? It seems every other boat I have had, I have left the pin in at some position. But the idea on the transom angle interreges me. I removed it completely because it looks as if there are some stop(or resting) pads molded into the casting of the unit.

paul, engine is centre, cav plate is level with bottom of hull. will have 2 redrill 2 lift. will try that , if your happy with your set up. what prop size you running. mine is a 19 x 14 and i think its a bit much, with 2 adults shes hard 2 lift in a heavy sea state it takes a lot of throttle. console is standard avon.
