Make sure the gasket thickness at fuel pump mounting surface is the same as what was removed. If you aren’t sure, use a mercruiser gasket, that should have the correct thickness. Best thing is to check the fuel pressure if you can
Also this could be mechanical advance related, clean that up if...
Just an update, there was no filter on the fuel suction tube, but the tube appeared clean with no debris. I tried the timing light, but couldn’t find anything conclusive when the problem would occur. With the engine running, I checked my voltages again in the low tension coil circuit, I was only...
Great ideas, thanks! I just bypassed the resistive wire with a resistor and there was no change. I’ll double check with a voltmeter as suggested and I think I’ll try to start it with the starting wire to the coil removed, then run it and see if that changes anything
I’ll try the timing light as...
I have a 1985 Searay with an I/O 470, mercruiser 2bbl (170). I installed a SEI 106 out drive about 20 hours ago, last November. The boat start and runs well cold or warm. It accelerates smoothly and idles just fine, shifting seems to working well. After about 15 to 20 minutes at cruising speed...
On or off the drive needs to be in forward so the the shift shaft will slide in or out of the shoe in the bell housing. You may have gotten lucky. it’s easy to have a brain fart in the heat of battle, I’ve come close to making that mistake myself.
The whole project took me around 25 hours including the removal and installation of the stern drive unit. It was actually kind of a fun project, but you need some time to do it. Someone suggested about 4 hours on a previous thread, no way! Also don’t forget to use a drop of high strength...
I changed both drain plugs on the heat exchanger since they were easy to get at and I had the coolant drain out anyway. I put them in and the lowered the engine to the starting position with the adjusting stud. I put the lower nut and jam nut back on, leaving them loose until I checked the...
I put the hose connector cover on and torqued it to fifteen lbs and cracked the cover in the process. Fortunately I had another cover that came with the impeller cover I got on eBay, so after another gasket cleaning drill I put this one on and just tightened it to what felt right and it hasn’t...
I ordered a gasket kit from Mercury prior to starting this and I used Permatex Aviation gasket instead of perfect seal on all the mating surfaces as I believe others have done. My timing cover went on easily, I tried to be careful to get it on evenly. Once it was in place the cam seals appeared...
My chain tensioner was worn pretty bad so I replaced it with a less worn one I found on eBay. The timing chain and gears seemed other were in good shape.
The exposed oil pan gasket was fairly intact and there was no gasket material on the timing cover, so I was more fortunate than others as far...
As far as the camshaft is concerned, I found the same deep groove under the front water seal as others have documented, and similar light groove where the rear water seal rode. I used a micrometer to measure the camshaft and came up with .873 and some change as have others, the low end of the...
I used a hammer and punch to remove the water seals and a hammer and PVC coupling to remove the front (oil) seal. I used a hammer and a device that was just slightly less than the diameter of the water seal cavity to install the water seals. I could not find a PVC piece close enough to the...
I’m going to try to capture all of the concerns pressing the seals in and out I came across in the various threads on this forum, that way there in one place. The timing cover has a lip on the back where the rear water seal seats. So the water seals can only be pressed or punched out one way...
I removed the timing cover and took a picture of the position of the cam seals. I wanted to duplicate this, particularly the front seal, when I installed the new seals so I could be certain they would be positioned over the speedy sleeve. My front seal is located at the base of the chamfer in...
