    Timing 1988 88SPL, Throttle Cable Hookup

    I am going through the tune up procedure in the original manual. The motor idles good at 700 RPM, WOT at 4900 but I notice that the carbs are about 5 degrees from horizontal when the throttle is all the way down. Also I have hard starting, just the first time of the day.<br /><br />The TDC...

    New thermostats have no slot at valve

    I just got the new thermostats for my 1988 88spl, and comparing them there is no triangle slot at the valve cap. The old one has a small triangle slot, should I add to the new one? What is the reason behind the slot and drawbacks of not having?<br />Thanks

    Poor Idling 1988 88SPL

    I have read alot of posts the last couple of weeks on the 90HP range idle problems. All of your hints finally made sense to me and my problem. The motor starts and then begins to "load up" and run rough. If I open it up, it runs on maybe 2-3 cylinders for about 15 seconds and then the third...

    1988 88SPL vs 1973 Merc 150 Inline 6

    I currently have a 1988 88SPL on a 20' Sea Ark Jon Boat and it runs well, about 41 MPH with a 19 pitch SS prop. I do have at my disposal a 1973 Merc 150 (my dads, it is in good shape). I know the lower unit on my 88SPL is 2:1, does anyone know what the ratio is on the 150 Merc? Engine...

    1988 88SPL Power Pack

    I have been having trouble with starting. I thought related to flooding, but through testing it appears that the left side cylinders do not have the spark that the right side has. After the motor starts, I use the timing light only as an indication of spark. I move the clamp to each plug wire...

    Hard Starting, Fire Shooting 88SPL

    I have been having trouble starting my 1988 SPL the first time, every time out. I crank it for a bit, and let it rest. When I finally get it to hit, it still takes a few more tries to get it going and then it starts easy the rest of the day. I usually prime the bulb until hard, and them some...

    Pin hole in fuel pump on 88SPL?

    1988 88SPL, owned for 2 months. Good compression, carbs rebuilt, new spark plugs. Hard starting, lots of smoke, idles like it misses, but runs good at WOT. Will idle good for 2 minutes after WOT, but then starts to miss and more smoke. After running last time, removed the spark plugs and the...

    Tachometer Hookup

    Where does the tachometer hook up on a 1988 88HP Johnson SPL? On my old 1973 150 Merc, there was a plug on the remote control. I see a plug on my johnson remote, but what are the connections on the motor? Any wire identification if using a temporary tune up tach? My book doesn't say.

    1988 88HP SPL

    Hard starting and backfires once before starts. Lots of smoke. Carbs have been cleaned, has proper jets. 115-120 psi compression on all cyl. <br />Will idle and run fine, is the smoke and hard starting normal? What would be a good tach to put on this motor? I've only had the motor for...
