S/N 05348445

The engine seems to run fine for the most part. But when I am running wide open about 6K rpm it seems to do fine when turning left but when I turn to the right it bogs down and I have to straighten out to get it back up to speed. It gets annoying when pulling the kiddos on their tube.

Also sometimes when I shut it off it doesn’t want to start. I usually have to raise the motor up out of the water to get it to start.

"Bogs down" could be related to water flow of the tubes. If you can not crank the engine sometimes (different to it will not start-that means the engine just cranks over without starting). My suggestion is to pay close attention to where the engine harness enters the outboard and see if broken wire. If you are skilled pretty easy to break open the harness and look for damaged wires if not just replace the boat/engine harness.

“About 6k rpm” is very close to the rev limiter.  Can you be more specific?  What prop are you running?  Also, clarify your no start comment. Does it crank and not fire or do you have a no crank scenario?

For me what comes to mind could be water ingestion from water coming off the pontoons or possibly a ladder.

Make sure your not ingesting water through the engine.

I believe the prop is 14x13. It had a 17 pitch before and it didn’t run over 5K rpm. The engine seems to run great for the most part. When I turn the boat to a hard right the engine looses RPM almost like it’s not getting fuel. If I straighten the boat back out it takes 30-45 seconds to build rpm back up. However, if I throttle back and slow the boat down and then go full throttle again it has all of its power again. If I don’t throttle back it takes the 30-45 seconds.

As far as the start issue. It does crank and crank and crank but it won’t fire unless I raise the motor out of the water. The is problem doesn’t happen all of the time. Just at random

But the hard right turns always bogs the motor.

Sorry if I’m not explaining it to well

What do you mean by ingestion? And would that happen in a right turn and be fine in hard left turns?

If there was a ladder on the right side and if you’re turning into a wall of water with the engine, it could be going up and into the engine air intake. Just bouncing this off you so you can look. It may only occur when pulling down and back when tubing so be sure to look with and without that influence.

Also the steering cable on the right, if you have cable steering, can deflect water coming off the pontoons in an upward direction.

Make sure your not kinking your fuel line as well which could be turn related.

For your cranking but not starting issue does this occur only when it has already been ran, only on hot days or are there any extra details you can provide?

Check the electrical harness, you could have a faulty electrical connection due to a broken wire, the trimming engine up to start could indicate a broken connection, good luck

Discovering a sharp bend or a kink in the fuel hose routing is the most common problem for a lack of power during a hard turn.

++ to all the guys above!  My money's on the "internally broken" wire.  The "raising the engine to re-start" tends to lean toward the wire, I would think.

The fuel line kink would act similar, but would take a while to empty the VST - wouldn't happen as soon as a right turn was initiated?

Thank everyone for their inputs. Hopefully after this Valentines (Wife’s Holiday) passes, I will get time to look at it. Honestly I didn’t even think about wiring even though I work avionics on airplanes lol. I will update once I get a chance to look at it.

You should also check to see if the engine software is up to date. There was one addressing hard starting released awhile back.
The engine has to have a fast enough and steady cranking speed to "lock on" to the crank sensor signal before it will start. If battery voltage to the engine is down slightly raising the engine to relieve exhaust back pressure may be increasing engine rpm.
