Default Any older outboard whiz? 1997 Ocean Pro 200HP

I have a 1997 Ocean Pro 200HP. I think the shift interrupter has gone out. Is this the shift interrupter (yellow arrow pointing to it)? It is on the RHS, next to the remote trim/tilt switch. It has a roller over it. When I press it down with a screwdriver while the engine is running there is no change of RPMs.

Oh, and I meant older outboard motors, not necessarily old whiz.

Thanks

Not sure but I think so. A lot of great members here and I'm sure you'll get the right answer if mines incorrect. I have the same motor. I'm curious what your symptoms are that leads you to believe you have an issue with the shift interrupter switch? Just trying to learn as much about my motor as possible.

Thanks.

Well it started when we went to go diving this morning. After 7 miles out in very rough seas, I came off a plane and we talked about if it was too rough. We started back up and and the boat wouldn't get up on a plane. Seemed like one or more cylinders were not firing. We idled back home and the engine ran poorly the whole way back. I thought I had fried a cylinder. We we got into some calmer water I tried again and it almost got on a plane but there was still something not right. Got it home and ran a compression test and all cylinders are right around 100 psig. So no blown motor. The engine has about 1600 hours. I sprayed some carb cleaner in the carbs (which have never been rebuilt) and it seems to run OK. Ran some OMC Engine Tuner and it is running better. But I started thinking maybe the interrupter was making it run on only three cylinders all the time by non disengaging. So I used a screw driver and pressed down on what I think the is interrupter and nothing happened.

Yeah that's it. Per the manual... Most carbureted V6 and V8 models are equipped with a shift switch that
is capable of cutting spark to one or both banks of cylinders in order to ease
load on the driveshaft while shifting. A malfunctioning switch can cause a no
spark condition on one bank of cylinders.
The first check (the Elimination Test) isolates the shift switch from the
ianition svstem to determine if the switch or charae coils are the cause of
spark loss to one side of the powerhead.

Pm me your email...

Do you have the fitch? This is the diagram for carburated. See wire colors and trace.

Spraying carb cleaner into the carbs does NOT clean them.

simplest thing to do is take a timing light and see if all cylinders are firing.... all 3 on the right side out, I doubt youd get even close to planning,,,

Oh the irony in your statement.

It sounds strong on the hose next to my house. I'm pretty sure all cylinders are working. I think maybe with the heavy seas, water may have gotten into the cowling and maybe shorted out the interrupter. But if I press the interrupter down, there is no change in RPM, so I think it may not be working. But it does shift into and out of gear.

I wonder with 1800 hours, if I should get the carbs rebuilt. Is this a hard job? I'm pretty handy, but all those linkages and getting them synced is probably beyond my level.

On top of the engine, there is a linkage rod that connects the 2 banks of carbs. When you advance the throttle, do both sets of linkages move? I had the screw that holds the 2 together back out on my 3 week old '01 Johnson on the way out of the harbor one day. Luckily the screw ended up right on top of the power head. Like you, there was no power when I tried to accelerate.

Hey you can just remove the interrupter and see how it runs, just be careful with the shifts.

I would definitely rebuild the carbs. About a $120 DIY job. I watched a YouTube video and did it in an afternoon. My shift interrupt switch went bad and the motor would shut off when shifting from forward to neutral. I unplugged the connector on the motor and it ran like normal.

Do you have adjust or sync the carbs after a rebuild?
