95 evinrude 90hp repair advice please

11 posts in this topic

I have a 95, 90hp evinrude with 650 hours. I have had no mechanical flaws with it up to this point thru 11 seasons on the water. Recently, I have noticed a slow but steady drip of gas on the water once the engin is shut down. It leaves a gross rainbow. My mechanic tells me the float bowls on the carbs are plastic and over the years have warped. He is recommending replacing the bowls and rebuilding the carbs and installing new jets. He quoted me about $125 in parts per carb and one hour labor per carb. So, I think I will go ahead and invest in the repair as I don't want a gas leak and I really have put no money into this outboard in 11 years. What do you think? Does this repair sound reasonable? How about the cost? Thanks for your opinion!

Sounds a bit high to me...... I think my rebuild kits were $30 apiece....

I dont see how the gas is getting into the lake unless it is overflowing on the carbs. If there is no obvious leaks around the carbs I would look at the fuel recirulation system and do a good decarb with seafoam deep creep first and see if that fixes it. Typical carb problems would be that the bowls overfill or the motor wont idle worth a crap.

Eurolarva, I am not a mechanic but today I popped the top off of my engine and there are 4 black rectangular structures, one for each carb and there is gas running down the side of one of them. It eventually lands on the inside of the engine case and seeps out the seem when the lower unit comes into the upper case. I hope I explained that ok. Thanks

The parts seem expensive to me. I would get another quote. You could probably get a rough estimate over the phone from another repair shop.

If I added that up right its going to run you between $800-$1000 for getting the carbs rebuilt. The labor sounds right but the rebuilt kits seem high. Three of the carbs are OK and one is leaking. The boxes you described are the covers over the carbs. Take the cover off and inspect the fuel line to that carb. Squeeze the bulb up on the fuel line and look to see where the leak is coming from. If its at a line then its an easy fix. Most likely its leaking out an overflow hole on the carb because of the float or crud stuck in the inlet valve. Either way the fuel level in the float is too high.

If it were my outboard I'd pull the one carb, remove the bowl, pull the float pin and inlet needle, and flush gas through it in case there was dirt causing the inlet valve to not close. Then put the inlet needle and float back on and check the float level and adjust or replace the float if its damaged. A shop manual will have all the info on the carb that you'll need.

Take this bit of information as well, then.

Your mechanic is spot on. This is a known problem with a few years of J/E v4's.

You have two carbs on this engine, so two float bowls, so you will need two new metal bowls. $125 is a good price, I paid more than that when I did it myself last year. THIS IS NOT A REBUILD KIT! The mechanic is not talking about the airbox. It is not a mis-adjusted float, and is not the overflow. 1 Hour per carb shoptime is good for this repair.

The plastic bowls warp from EtOH in the fuel over time, and are not flush with the carb. You can't just put a new gasket in, you can't put them on a flat plate and make them flush - just pony up and buy the new ones. If your boat is leaking bad enough that you see it with it trimmed down, you definitely need new bowls. Mine would only leak when trimmed up in the trailer position.

You will also need 1 new high speed jet (I think it was the high speed) per bowl. Plastic bowls were threaded 1/4x20, and the jets for the metal ones are threaded differently. It was going to take awhile for them to get the correct jet for me, so I just tapped out the new bowls for the jets from the plastic bowls.

It is a fairly straightforward swap that the average guy could do themself if you are so inclined. Take your time, and get yourself a repair manual, and it isn't difficult.

Heck, if you decide to do it yourself, I have repair manual you could borrow if you are in the metro area.

(edited - I see you are in IN, check with your local library for a repair manual)

My bad, I said 4 carbs and know better then that. That'll bring the price for repair in the 4-5 hundred range.

Tim, thats for the clarification on the warped plastic bowls.

Tim, Frank and others - thanks again for this valuable information. I am not mechanically minded and I really appreciate your insight into this problem. I will let my mechanic repair this. He did mention the new bowls were metal. I think spending $1000 on this boat after 11 years of service is justifiable. It is a 1660 Pro-V and fits my lake perfectly. The lake is 375 acres of panfishing with a little tubing and swimming mixed in. Thanks again.

      I am definitely in! My boss also gave me permission to start looking at jet boats this spring. We have to get rid of a 3rd car first but I do believe a Lowe 1760 pathfinder with a 115/80 will also be in my future!

      Eskimo cs is top notch. I have had 2 different pop-ups and have a 949i now and love it. Wasn't overly impressed with the flip over pop-up at Cabela's though. It seemed to have less room out in front of you than the other flip over from clam and otter.
