Moter

[zipperrck]

I have a 1969 85 Hp two stroke Johnson V4 moter on a 1970 15 ft. trihull carvelle.<br />At low speeds the moter runs rough. At high speed the hot light comes on but there seems to be no difference in how the moter runs. When I go from 0 to full throtal I have hesitation. If I move the speed up slowly there is no hesitation. Max speed is 30 mph. Is this the normal high speed for this boat and moter?<br />As this is me first boat I am unsure if all these conditions are normal for this moter.<br />Also, do all outboard moters pump water out? I can not see this happening on this moter.

Re: Moter

zip - - - - DO NOT RUN THIS ENGINE UNTIL YOU HAVE REPLACED THE WATER PUMP - - Without cooling water circulating from the water pump your engine will overheat to the point that it will freeze up and will only be useful at that point as an anchor. It WILL happen if you continue to run it as is.<br /><br />Replacing the water pump is not that big a job.

Re: Moter

The first step in that process is to obtain a service manual specific to your engine. If you don't want to buy one, check your local library.

Re: Moter

Based upon his question...the best advice we can give him at this point is to seek a reputable dealer for repair- he needs some time to gain more knowledge before digging into a service manual...<br />and...<br /><br />Zipper-<br /><br />If you did not cause significant damage to this engine, you will have dodged a bullet. Research these boards. They are a wealth of information. Let us know how you made out. Sorry to hear what happened...

Re: Moter

Thanks for the info. I will NOT run the engine until I replace the water pump. I will let you know the outcome.

Re: Moter

I'm helping Zipper with his water pump job. Were looking into buying a clymer book for the motor. Can anyone send us a diagram or a place to buy the book. Not a whole lot of summer here in Central NY! Thanks for the help

Re: Moter

I would suggest you pay the little bit extra and get an OEM manual. Has a lot better explanations and pictures than Seloc or Clymer, especially if you are not very familiar with outboards.

Re: Moter

Okay, I have purchased the OEM Manual. I'm looking for a parts diagram, parts list and or a diagram thats alittle easier to read than my OEM Manual that Zipper and I have purchased. Can any one direct me to such one. I have seen many diagrams for other moters and I/Os. Thanks for the help.

Re: Moter

I have the Evinrude version. Just follow the directions in the manual for gearcase removal. When you get it off you'll see the water pump on the driveshaft. The shift wires are under the hood on the rear starboard side. Tie a string to them before pulling the gearcase down.
