Finally on the water after 5 months. The Ulterra installed and working. The engine is not overheating now.
WOT issue (or on plane): The engine jumps on occasion. It is like I hit something in the water on occasion. The engine just jerks some. This is just on occasion. The engine is running with the cavitation plate just at water level.
The engine printout shows no faults.
Any help would be appreciated. It is a 2011 30hp Merc 4 stroker.
Rubber hub in the prop may be trying to go bad.:twocents
New prop. No dings in prop. Merc 4 blade aluminum.
Since this is a new rig I'm wondering if the shift cable isn't adjusted properly and it's not going all the way in gear.
That is a possibility. I rigged it. I will have to pull it out of the water to check it I guess.
My neighbor can hear the click in the lower unit fwd and rev. Everything looks good under cowl. Easy shift fwd/rev. This don't mean it is rite doe.
Unhook cable from shift lever on motor. Get it in neutral with that lever. Put connector up to shift lever. It should center on hole in shift lever with out moving anything to connect. If it does not, adjust cable end until it centers in hole. Sure sounds as if it could be poping out of forward. Also could be a miss fire but looks like that would show on computer.
ok. I will beach it late this evening and wade around and check it when the squirters leave.Quote:

Hopefully resetting neutral will solve it for you..think cray has it.
Have you watched the tach to see what it does when this happens? Know that would be hard if its quick and you are not able to reproduce it...just thought I'd ask.
Did as Cray stated. Everything looks fine. Shifter moves correctly, not binding. I left my portable dashboard art home, so no tach today. Will drive around later when the traffic calms and take notes.
This engine has the easy shift. You can shift it with 1 finger when the shift cable is disconnected.
Ok, while you are playing try this one. Put it in forward with cable disconnected, engage the shifter into forward and do the same alignment check with pin to hole.
Does it feel like you hit a log with the lower part of the motor? Check your lower unit oil. Check for metal shavings. Had the same thng happen to my Johnson. Would be going down the lake and all of a sudden the motor would act like it hit a submerged log or rock and lift up. Could go another week or so and nothing happen, than same thing happen again. The dog gear finally went and lower unit seized up. Had to replace lower gears.
Next time Cray. Had to put it back together because of rough waters and we are going home for a few days.Quote:

Only difference was that I had an extra passenger yesterday. What a difference a day makes.
I am sure this problem will return sooner or later.
Thanks for the help and all the info.

Rpm???
Rpm when this happens?
No tach. Tach at home in my duffel bag.
Check rpm when it happens.Quote:

The tach is a good idea , just to track it and see if it's always in the same zone. Wish I had thought of that !
