I am looking for a diagram, and or some help with assembly and disassembly of valve. This is lower valve for Prestolite pump. It has ball bearinigs and a spring. I need to service this unit. Thanks!
I have a 77 - 115 which I believe has spent most of its life in fresh water. I have used it quite a bit in salt, but always flush it out thoroughly (for 1.5 yrs). Pending some other diagnosis, I may need to remove the heads. Heads do not look like they have never been off as the paint is...
I have a 77 - 115 which runs fine and can run all day at 3/4 throttle. On last two outings I opened it up (WOT) for a very short instance and the alarm went off. It has a 1yr old water pump and flows great. Looking for advice.
I have been in the process of replacing the water pump on a 77 115. I have the dual tube type. I have the guide tubes, but I tried fitting the small top pump plate into the middle section and it does not look like the copper tubes are long enough to go past the plate into the seals. Does this...
I bought a boat with 115ETL77 on the mount plate ID tag. While asking some questions about a water pump question on a FB group I was informed by the group members that the powerhead is not a 115 but a 135 becase of the rear exhaust hump. Nothing looks touched on this motor bolt heads etc. So I...
I have been in the process of attaching a tach to my motor. I haven't bee able to get a legible reading on the multi-meter. When I touch the ground/black lead (only) to the ground on the motor gives an un-readible readout. It almost looks like it jumps around based on engine pulses, but this is...
I am rebuilding the fuel pump on a 99 40hp ELPTO. The kit comes with white (plastic diaphrams - check valves) and Black rubber diaphrams. Which do I use? Manual say one is for design 1 and the other design 2. It does not tell how to identify the design you have. I have found a lot of mixed...
I have a 1999 40hp elpto. I have been having oil slowly draining into my intake manifold when stored. It then drips out through the carbs if stored tilted or remains in the intake and eventually out of the center section of the motor and out one of the water holes above the lower unit if stored...
I have been trying to track down an oil leak. I have had mystery oil leak that after sitting for a week or so after running clean new oil was coming out of the top weep hole of the lower unit (This I found is an exhaust tube drain). Also was loosing quite a bit of new oil and a heavy smoke at...
I was removing the shift shaft on my 99 40hp outboard. The detent spring bolts (2x) 8mm broke off at the head. There is a small amount of material sticking out of the lower cowling posts. What do I do?
Is this detent spring necessary? - Will it run/operate without it?
Can I easily remove the...
