    1990 force 120hp hard start/no start

    Hi guys! Looking for some help here. I have a 1990 maxum 2100 LDC (l-drive) 120hp. It sat for a couple of months without running and when I went to start it up on the hose it did not want to fire up. The battery is fully charged and the motor turns over wonderfully (around 500 rpm) but I'm...

    1990 force 120 lacking power

    My l-drive 120 hp force is lacking power at WOT. Compression is 125 on all cylinders and the motor starts, runs, and idles perfectly. My problem is trying to plane and maintain cruising speed, on good days I can turn around 4500 rpm (used to do 5200) and on bad days maybe only 4200. My...

    U - Joint bellows torn 1990 l-drive

    When I trimmed down to change my prop shaft seal last week I noticed the u joint bellows was torn and water was getting in unwanted quantaties (hey, at least with the l-drive the hull still floats!! :)). My question is: Can you change the bellows without removing the powerhead and dropping the...

    ignition testing question

    I've used an in line ignition spark tester to verify that all 4 plugs are getting spark on my 1990 force 120. My question is, does this necessarily mean that the plugs are firing, or just that they are getting power from the coils. The engine starts and idles fine, but maxes out at just over...

    hydrofoil on an l-drive?

    I recently was given a brand new hydrofoil by a buddy. I was considering installing it to help plane (once I get the motor running right of course!) but am wary about using it on an l-drive setup. looks to be fine when trimmed down, but it seems it would interfere with the transom if I were...

    getting hit in the pride hurts worse than funnybone!

    I take a great deal of pride in my solo launching/retrieving abilities, usually being able to launch, park the truck, and pull away from the dock in 3/4 minutes. Every once in a while though I get humbled a bit! (deservedly so!) Last time I went out to a ramp I'm unfamiliar with and it was a...

    force 120 running poorly!

    Looking for some ideas here. After extensive work my motor is starting fine and stays running at idle. On the hose everything seems perfect. When I went to the lake to test, I'm having problems. Motor is severely lacking power and takes a while to plane, and will max out at 4400 rpm/30 mph...

    overheat buzzer test

    can anyone tell me the best way to test my overheat buzzer? (1990 force 120 l-drive). It has never sounded at startup when I put the key in the on position, but it has worked in the past (sucked up a rag one time and pinched hose the other). I have not heard it in years which is great but...

    Force 120 l-drive flooding?

    I just completed my top end rebuild for the powerhead on my 1990 maxum 2100 ldc with force 120 powerhead, replaced all 4 pistons and rings. Reassembled and reinstalled and she fired right up. Had a great day on the lake two sundays ago, engine fired up every time and no longer stalled when...
