this new to me whaler has original setup of johnson 235 and alum. 14 1/2 x 19 prop and in first use seems to operate well, but puts out twin ( v shaped ) roostertails at all trims - in smooth water. does anyone recall what your prop was with this motor? thanks

I'll have to look at what I have on my Outrage 22' with 225 Evinrude, but I THINK it is the same as you mention. What is your RPM reading and what is your speed at WOT ?
I'm really having a hard time thinking that your prop is causing these rooster tails no matter what size it is, unless your motor is trimmed up (out) too high or is raised too high. Do you have trim tabs or transducers or something else on the transom that is in the waterflow from beneath the boat, or something odd bolted on to your cavitation plate?

My friend is having the same problem with his 200 HPDI on his '85 Mako 224. We are going to raise the motor up a hole or two form the lowest mount and see what happens. It stops at extreme trim up but by that time it is really porpoising.

Good point - could be the motor is set too low, rather than too high.

Worth a shot. My friend's cavitation plate is totally submerged while on plane. Maybe take a look over the stern while underway. Definately dragging around a ton of lower unit in the water.

The prop has little or nothing to do with the roostertails.
As has been suggetsed, the motor is too low. Raise a hole or two and see what happens.

My 22' OR w/225 Yam is one hole down.....thats a 25" shaft motor.

Agree - A vee shaped spray off the engine is always a sign of too low motor mounting. Raise one hole, at least.
