    1990 Evinrude 70hp no water at tell tale

    I just replaced the water pump and still get no water at the tell tale when on the muffs. Is this 'normal' when on muffs? The prior owner said it would not do it for him either but that it poured out when in the water. Thoughts? The port has alredy been moved to the top of the exhaust housing...

    I am replacing a water pump on my 1990 Evinrude 70 hp VRO. I am reassembling but cannot keep the o-ring on the pump housing in place. Any tips would be greatly appreciated.

    Can't drop lower end on '90 70 hp VRO Evinrude

    I just picked up a boat with a 90 VRO 70 hp. It has sat for 3 years and the prior owner included a water pump kit. As the new owner I want to replace the water pump before using the boat so that I know the maintenance schedule. I have removed all bolts from the cav plate and trim tab, and I...

    1985 15hp Johnson no telltale flow @ low idle

    I have replaced the impeller because the telltale was trickling. Now when it runs I only get flow from the telltale at high idle. When I throttle it down the flow stops. Any ideas before I venture to the gromment under the powerhead? ~Ken

    Conflicting advise on head gasket

    I am reinstalling the head on an 85 15hp Johnson. I have received conflicting advise and was curious to see if there was an experienced OMC mechanic in this group could clear it up. The OMC gaskets have a self-sealing compound on them and have traditionally require no sealant or adhesive for...

    Head bolt/gasket questions for '85 15 hp Johnson

    I am reinstalling the head on an '85 15 hp Johnson and needed to know the best way to clean the surfaces for the new gasket. I heard oven cleaner works...though it removes paint, too. Any other recommendations? Also, what is the proper torque, and would it be prudent to use thread locker...

    15 hp 85 Johnson compression issue

    My 15 hp Johnson has low compression; ~60-70 both cylinders. It also has low flow out the tell-tale (I replaced the impeller with no real effect and will check the gromment on the water tube shortly). Hoping for the lesser of possible evils, I checked the head gasket hoping that a warm engine...

    How to remove head on 85 15hp Johnson

    I have an 85 15hp johnson with low compression. In talking with several local mechanics, if it is anything more than a bad head gasket, the engine is now an anchor...at least by what they charge hourly. One mechanic's suspicion was that the low water flowing out of the tell-tale was indicative...

    Need help troubleshooting an 85 johnson 15hp

    I have a 85 Jonhson 15hp (J15RCOB) with low compression (60 & 70, spec is ~115) and low flow out the tell-tale. I have already replaced the impeller, which made a small improvement in the tell-tale flow. I have receive mixed advice on decarbing and I am leaning towards not doing it as the...

    fuel:oil ratio for 2001 GTX RFI break-in

    I just rebulit the top end on my GTX and was told to run premix to break in the rings. What fuel:oil ratio should I use since the engine already has oil injection? 50:1?

    I have a 15hp Jonson (J15RCOB) that tests ~65 & 70 PSI. After just rebuilding the top end on me jet ski, I am not sure I want to tackle replacing the rings on this engine. How involved is it?

    Seadoo Dies at speed

    I picked up a 2001 GTX RFI with 21 hours on it. Showroom condition. The first time out it ran a little rough at low rpm. It seemed to work itself out once I got up to speed. But then it died after about 5 minutes while going ~30 mph. I brought her home, changed the fuel and the plugs. Now it...

    Shift linkage

    While replacing the impeller, I noticed the threads on the bolt in the shift linkage was pretty well stripped. :( The block was somewhat damaged but still has threads. Although the bolt held fairly well when taking it out, it fails to grab sufficiently going back in. What's the easiest fix? I...

    Correct rotation for impeller

    I installed a new impeller in an 85 15hp johnson last night. This morning I woke up and something didn't seem right. The shop said to slide the pump down and turn it clockwise. But this twists the fins CW and I seem to recall reading somewhere here that the shaft turns CW. This would mean the...

    Is this typical?

    I am in the middle of replacing the impeller on a 85 15hp johnson. I noticed there is a bit of back-lash between the shaft and the prop. Is this normal? The prop turns when I turn the shaft with no slop in the forward direction but there's a bit of slop if I hold the prop. Also, when spinning...

    85 15hp johnson drive shaft installation

    Well, I was halfway through changing the impeller when the drive shaft slipped out part way. :mad: Urrgh! It appears that the lower pinion gear comes off when this happens. I am trying to remove the prop shaft/bearing housing in the lower end but it will not come out. What's the trick...
