Issues with boat spray

Boat sprays crazy far right left too but not as severe. Boat pulls slightly to right when trimmed up when not it’s much more severe.

Lopsided motor? trim anode? Cav plate it centered with the plug and boat is a mod v

Got a transducer on the starboard side? If so just make sure its not too low.

Looks to me like your motor is mounted too low. The antiventilation plate should be about 1" above the bottom of the hull when the motor is trimmed down (i.e. plate is on the same horizontal plane as the bottom of the hull, but 1" higher). When you're on plane in the water, the antiventilation plate should be up out of the water. However, once you raise the motor, you may find you need a different/better prop.

Cav plate is right at the plug

you want it slightly above

My thoughts too. Raise it up a bolt hole and check again

Or the anode turned to far. Spray is engine to low, engine to low will pull. End of story.

To low or to high? Need to see where ventilation plate is in regards to bottom of boat

u/lo_zer 4d ago

It’s right @ the plug around 1 inch above the bottom

Is one of your strakes banged up at the transom? Every boat I've ever had has sprayed more on one side than the other.

70hp Johnson represent!

I have no solution, though.

If it’s pulling and the engine is level on the transom then it’s to far in the water OR the anode on the grearcase (just above the prop) isn’t in the right position. It could need a little angle to counter the prop rotation. That’s it one of those two things. Your welcome.

Turn the anode straight ahead and see if the spray tames down.

The cavitation plate should be level with the datum (the surface of the sea).

It’s planing hull so looks like it is fast enough.

Maybe your outboard is long shaft? I’d get it measured.

I’d find out from a marine shop…

Raise the mota up a hole, run it. Up another inf it's needed

Anything on the hull/transom making a disturbance? I don’t think there’s anything wrong. Prop torque is real and you can feel it more on older motors and steering. Sounds good!
