    1964 Evinrude Starflite 70hp impeller change

    To change the impeller you need to remove the LU. Pull it from the engine and for example put it in a vice. When removing and putting it back I would suggest you to use a floor jack. I use a floor jack when pulling and put back lager LUs.

    Hydraulic cylinder rebuild

    Sorry but I do not know what pump you should buy if you have to change it. Search at Ebay for OEM pumps. If there are pumps on Ebay and they are Chines made, do not buy them! Starters for Chrysler/Force and made in China are crap, but cheap. Do not buy them, rebuild your OEM starter (Prestolite...

    Hydraulic cylinder rebuild

    #Lou C that was a nice work, well done. T&Ts are often a PIA to deal with, change o-rings and seals can be done if you get it apart. The pump with all check valves, springs and steel balls is a no no in my opinion. #Captndrydock good luck with you work.

    Force 40 issues

    The machine shop has to mill off the same amount of material at the edges until all three edges are clean and they are perpendicular. It is important that all three edges are even in size so that the dogs at the clutch and the gears are in contact when engaged.

    71/72 105hp Propeller Clearance Issue

    Did the "new" LU come without the exhaust snout and you put the one from you cracked LU on it? I know there were two different snouts and the later LU from mid 70:es hade a snout which was shorter and had a steeper shape. When I check in my parts catalogs there are different part numbers...

    New to me 18 hp Evinrude.

    Bman2895 have you pull the flywheel and check the points, cleaned them and set the gap and looked at the coils?

    New to me 18 hp Evinrude.

    Checking for good spark you need to se if it can jump 3/8 in or more in atmosphere. Checking for good spark with the spark plugs is not good enough. Then as Crosby says pull the flywheel and check. The coils at those old OMC are know as dry out over the years. If good coils then clean the points...

    Attempting a motor rebuild

    Captndrydock source for parts for your rebuilt is Franz Marine service. He might not have the Wiseco pistons if you have to change pistons. Franz was a dealer back in the days and now he is 80++ and want to sell out all and retire. He has or can give you advise where to find parts for your...

    1980 9.9 hp Chrysler no spark-need some advice

    tmcook this thread is 16 years old. Start a new thread about you issue. BTW The prime side of the ignition coil should read about 1-3 Ohm. Secondary side about 6-8 kOhm. No spark issue are often dirty points, clean and set them at 020 in. Also check the spring in the HT rubber boots for rust.

    My flywheel came apart at the bottom where some metal blades are stacked together any idea why?

    In my opinion you should be able to use the CDI stator with different triggers which are for Prestolite CD-modules. The trigger sends signal to the CD-modules to discharge the capacitor voltage to right ignition coil. The stator charge the capacitors in the CD-modules. The stator and the trigger...

    Force 40 issues

    When you rebuilt the LU did you changed any parts in it? These LU do not have any shim at either prop shaft or drive shaft. But there are two thrust washers at the prop shaft. One at each gear in front of clutch dog between the gear and the prop shaft. Are they in the right place now? If you...

    1990 Force 120HP no spark NEW stator tests 0.5V between sets open resistance this is crazy HELP

    That inner magnet/laminated core for the triggers does not looks good. You have to fix that otherwise it will chew up the trigger assembly again. Best is to change the flywheel, in my opinion hard to fix that magnet/laminated core in that flywheel.

    1979 80HP Mercury

    When you are in the lake (water) you have back pressure from the water to the exhaust. On muffs.......no. As jimmbo and racerone says, check the compression and check for spark at all cylinders.

    1991 150B force outboard no spark

    Do you have Prestolite ignition system with three blue or black CD modules? Or do you have Mercury Thunderbolt system with one switch box? Normally the CD modules or switch boxes can not be tested from resistance with a VOM. You test for voltage from the stator and triggers to the CD...

    Not really hard to pull apart. Just to be careful when pulling the propeller shaft cover. Make a puller for it, do not twist the cover to try to turn the cover a bit and try to pry the cover off with a screw driver at the mounting tabs. Really large risk you brake the tabs.
