johnson model no.?

[SYCHOWAND]

hi im trying to identify the exact model and year of my johnson 90 v4 twin but i cant seem to find a model number anywhere! have been told its on the shaft but cant see a thing! the boat its on is a 1991 model and would imagine the engine is about the same age. the only number i can see is under the cowling on an oval plate on the engine block which is R8616146 any ideas?

Re: johnson model no.?

Look on the port side of the transom bracket and post what you find.

Re: johnson model no.?

If you take the cowl off and look down at the top of the engine, see if there is a round, shiny nickel/quarter sized plate, if it is there, you should be able to cross reference the Jxxxxxxxx and come up with the model #, I think.

Re: johnson model no.?

Should start with a J90xxxxxx
Did you find the plate on the transom bracket ??

Re: johnson model no.?

I think that the "R" prefix means it is a factory rebuilt (or replacement) powerhead.

Re: johnson model no.?

That is probably a replacement powerhead number. Try posting some photographs of the cover and engine, etc, someone will probably be able to ID it for you.

The welch plug should be round, convex, nickel-sized, but not oval.

hi thanks for that are seloc the best manuals? even their site is confusing still not sure what book to order! thanks again

Re: johnson model no.?

If you want to do your own maintenance on that motor, you will want the factory service manual that specifically covers it. Seloc and Clymer are good manuals for general purposes but are too broad in scope and cover too many models to be much help.
