1988 Yamaha 175 - Bogging down after running

[Ed]

Does a 1988 175 Yammie have a VST tank? If so, you may want to check the filter on it. Dirty VST filters cause the engines to bog down in the mid rpm range.

I used an external tank with fresh gas and the same problem exists. When first started it will run nicely and will move out good, can reach up to 5400 rpm. After running for a minute or so, and after the engine warms up, it starts to bog down. Feels like not all cylinders are firing. It gets progressively worse as I run. At that point it can't get above 3900 - 4000 rpm. A new development last time I was out, it seems I can get a whiff of what smells like melting electrical wire coming from under the cowling.

Anyone know of a good Yamaha Mechanic down near or on the Cape?

If you can get the engine warmed up at night when it is completly dark, take off the cowling and see if their is any "fire works" around the plug wires (bad plug wires leaking electricity to a ground)

Rich,

Try Peter Olsen at Bayside Marine in Westport. He's a great guy, and really up on the Yammies.

My cell phone took a swim so I don't have his number handy but it should be listed. If not let me know and I'll find it for you.

Cheers,
Bob
