    OMS help needed

    1994 Johnson 120 TLERC Noticed my engine seemed to be clicking loudly at idle on the water and I think shook a bit more at low rpm than normal and maybe a bit sluggish. I never got an alarm. Brought in home and started it on the hose, noticed no smoke, and shut it down.Began reading that the...

    '94 Johnson 120 hard miss

    Replaced the Power Pack and plug wires over the winter and finally got it out for a run today. At 3500-3800 roughly, there seems to be a hard miss. I can back the throttle down just below it and it ran perfect up to 3500 and cruised a couple miles. Throttling up, As it started to push over in...

    Mercury 20hp carb id

    After 20 years, I've decided to dig this motor out and try to get it running. This is a frankenmotor my Dad put together somewhere between 1975 and 1980 and my brother and I ran the prop off it as kids on an old 14' jon boat. The motor was running when shut down and stored 30ish years ago in a...

    Problem with new power pack

    1994 Johnson 120 looper V4. Noticed late last year that there was a no start issue occasionally. Before the season this year, I traced it down to a short/internally broken black/yellow kill wire as it goes into the resin on the power pack. Instead of fighting a 25 year old pack, I ordered a new...

    94 Johnson 120hp no spark

    Backstory- End of last season had an intermittent starting issue. It was either fine, or had no spark. Pulled the power pack up and Found the yellow wire with red stripe had more almost through against something. With the pack loose and no major bend in the wire, it would start and run. Bend...

    Temp sender on 120 Looper

    The tan wire on the port head on my '94 120hp looper has corroded and come off the sender behinf the plastic or rubber cover, effectively disabling temp alarms. It looks like sender is NLA and NOS ones still floating around are $$$. I haven't pulled it apart to look yet, but Is it possible to...

    Shorelander Grease seal

    My 1994 vintage Shorelander trailer uses an odd grease seal with an ID or 1.75 as opposed to the standard 1.719. I suspect this is due to the stainless replaceable wear sleeve on the spindle's seal surface. Could I use a standard seal in a pinch if I removed the wear sleeve? I sthe sleeve that...

    New tow vehicle for a fairly new to us boat

    The boat is a Lowe 2200 Aluminum deck on its original single axle trailer with surge brakes (completely rebuilt the brakes last year). It's a lot like a pontoon top on a 22'x8' v-hull jon boat. I had it weighed a few weeks ago and with about a half tank of fuel, it came in at 3540 lbs and the...

    Spin on fuel filter

    Johnson 120hp Looper Idle problems

    Last year, bought nice boat that has a 1994 Johnson 120TLERC. This boat sat unused for at least 6 years. I cleaned the fuel out, replaced filters, etc and jot it running for a couple trips to the lake last fall and ordered a set of carb kits. This year, it was stumbling at idle, so I cleaned and...

    Apparently did something wrong..

    1994 Johnson 120 looper. Bought it a few weeks ago, hadn't been started in 4+ years and fuel was likely that old. After bypassing a bad safety switch, finally managed to get it started and let it run for a few minutes. Shut it down at that point. Drained the old fuel and put a new in-line...

    New to me 1994 120hp Johnson

    Picked up a Lowe deck boat last weekend that has a 1994 120hp V4 Johnson, J12TLERC. I'm fairly well versed in my old 1976 85hp Johnson crossflow V4, but this 120 is huge in comparison. I'm assuming it is about as bulletproof as most any other OMC v4, but are there any issues to watch out for...

    Power steering retrofit

    I have a '76 model 888 Mercruiser without power steering. Is it possible, within reason, to retrofit the power steering off of a donor boat? My area is full of junk boats with 4.3's and 470's. I know I may need to fab a mount for the pump, but I'm more concerned about mounting the assist...

    4.3 with q-jet

    Helping a friend work the bugs out of his boat that seems to run way rich. The engine is new (used to be a 175hp or so Mercruiser 4.3, 1991 vintage I think). Replaced with a 4.3 balance shaft motor with a 4bbl cast intake and remanufactured q-jet. Does anyone know what Mercruiser used in this...

    4.3 conversion ignition

    Old motor: Mercruiser 4.3 with I believe a T-Bolt IV ignition New Motor: 4.3 rebuild from a '96 S10 (true vortec + balance shaft) To avoid having to deal with an electric fuel pump since the 96 block has no provision for a mechanical, would the newer balance shaft crank fit the '90 block...

    4.3 Mercruiser Noise

    Helping a friend with a 1990 4.3 Mercruiser. Motor history is unknown, but was supposedly rebuilt a year or two ago. Starts and runs ok, but has a loud ticking/knocking accompanied by a loud metal on metal sskreak/scraping that starts about 30 seconds after starting. Tick/knock is very...

    Smart tab retractor kit

    Has anyone tried these to see if they get the tabs up high enough to not make the wake mushy? I like the wake better without the tabs, but prefer them when cruising.

    Building a tower

    I'm thinking about building a tower for my '76 19' Glastron. Given my skills and tools, aluminum is out. I've seen a number of DIY towers on the web built with either 1.5" or 2" EMT. Is EMT strong enough? I would essentially want two top bars something like the photo below. (the boat in this...

    Waketower designs

    I'l looking at adding a waketower to my boat. I really like the looks (and price) of the single top bar towers, specifically the Joystick Pro series or the aerial ascent. Are these towers stiff enugh? Anyone have one like this? There are a number of vendors that have similar style towers I know.
