    2120 150TXRC prop?

    Looking to find out what prop folks might be using with similar hull / engine. Curious what WOT RPM you may be reaching. For a while now (years), my WOT max RPM has been running a pretty consistent 4800 rpm. The last inch or so of throttle produce no increase in RPM. Adjusting trim angle...

    2120 privacy curtain hangers?

    Anyone know what those little plastic hangers that are sewn into the privacy curtain are called? Mine have broken and haven't got a clue as to what I'm looking for. I'm guessing I can probably find something close at one of the sites serving RV stuff if I have an idea of what they're called. But...

    Intermittent engine issue - stalls at idle, low WOT rpm

    '04 Yam 150 carb 2 stroke OK. Launched boat back in mid-June. Ran good for 2 short trips. 3rd trip, got into the bay on plane for just a few minutes and RPM suddenly dropped from 4500 to a labored 2200-2400 RPM. Limped back to the dock but in neutral RPM drops and engine stalls. Engine would...

    Mixing 2S oil

    Thinking of switching from Yamalube 2M to Pennzoil ('04 carb 150). Any issues with adding the Pennzoil to the Yamalube still in the tank? Thanks

    Pilot screw turns out?

    Does anyone have the pilot screw turns out spec for 2004 2 stroke 150TXRC? My Yamaha service manual has the other carb spec's, but for some reason doesn't have that line. Seloc manual has 3/4 to 1-1/4 turns, which sounds like it may be about right but need to verify. Carbs were rebuilt 2...

    Bad rubber in rigging grommet?

    Anyone hear of a problem with rubber deteriorating at the rigging grommet? Years ago I added an engine temp gauge with left and right temp senders wired so I can monitor each side at the helm via a toggle switch. Last season, the starboard side stopped working so put it on my 'to do' list...

    Seafoam motor treatment? Or Stabil?

    Anyone use either, Seafoam or Stabil Marine in the tank with other additives? Carbs have gummed up on me clogging main jets ('04 Yam 150 2 stroke), so having them cleaned and rebuilt. Have already been using RingFree and Startron regularly, but curious if adding something new to help keep...

    2 stroke oil tank?

    Just curious if anyone has a feel for whether or not there's a finite life for the oil tank that's in the bilge? Reason I ask is my last boat had a Mercruiser I/O and the power trim unit was located in the bildge area. After 8 - 9 years, the poly-whatever plastic tank cracked and leaked all my...

    Lenco how to?

    '04 2120SC After 9 seasons, I finally have my first Lenco actuator failure. I have a replacement on order, so now looking for experiences of what worked well, and what mabe didn't, on snaking the cable of the new actuator into the boat. After removing the screws holding the upper bracket to...

    Aftermarket trim/tilt unit

    Took a shot at replacing the dust seals on my trim cylinders this past weekend. I guess it was an omen when I spent 2 hours unfreezing the manual release valve before I could get started. End caps soaked in PB, hit it with heat, broke 3 sets of pins on the OEM spanner, 18" breaker bar, electric...

    trim cylinder seals

    2004 150 carb 2 stroke (150TXRC) Finally got to do my mechanical checkout today. End cap seals on both trim cylinders are dried out, and popping out of the end cap. Tilt cylinder seal doesn't look the best, so probably time to do all 3. Looks like the trim cylinders shouldn't be a problem...

    Tow vehicle for 2120

    My V8 Explorer is finally giving signs the end is probably near. Curious as to what others think how much tow vehicle would really be needed with my trailer rigged with an Equalizer weight distributing system. I'm in the market for a new vehicle so pricewise, what I'm comfortable with all seem...

    Fuel issue, maybe?

    OK, time to look into those crystal balls a bit. I had a transient issue on Sunday evening with my '04 Yamaha 150 carb 2-stroke. Ran fine for about 40 minutes when all of a sudden I lost power and RPM's. Crusing smooth at about 4500, I suddenly dropped down to a rough running 1400, or there...

    Horn repair

    This is another one of those topics that has probably been beaten to death, but just curious if this has already been tried and what the end result may have been. I know some have changed the location of the horn so it doesn't catch water and some have angled it down to help them last longer...

    Routine fuel pump maintenance?

    Just wondering if anyone does regular maintenance (replacement or rebuild) to the fuel pumps? I've got the 2004 150 carb 2 stroke, and just wondering what the life of the internals on these pumps might be. I've only got a couple hundred hours on the engine, so running time might is probably not...

    Trailer brake maintenance

    This is my first trailer with brakes and having never had to deal with them, I'm thinking there's some kind of maintenance I should be doing in the spring time. I've got my 2120 on a 2005 5 Starr dual axle, single axle brakes. I only trailer a couple of local driving miles (40 mph tops), so the...

    Airmar install

    Any tips on doing an Airmar P79 install? My Lowrance transducer has crapped out again so I've ordered an Airmar. This is my 3rd transducer since '04 and I'm not putting another Lowrance on since they don't seem to last for me. John S. 2120 Sport Cabin

    Rubrail repair

    Some recent stormy weather, rough water and a too loose dock line caused me to hammer a piling pretty good. My rubrail took the brunt of the blow and a small section, about 15", pulled free. I've got a few broken screws and a couple pulled right out of the hull. What's a good way to repair...

    White smoke after launching?

    Anyone ever notice white smoke coming from their engines after launching in the spring? I just splashed this past weekend and motored my boat from the marina where I had the bottom painted to my regular slip. It was about a 10 minute boat ride at cruising speed (4400 rpm). The engine started...

    Testing GPS on combo unit out of water

    I've got a Lowrance GPS/Fishfinder (LMS-335), and need to test that the GPS is working OK. Anyone know if I can run the unit without frying something in the sonar with the boat on the trailer? GPS worked fine all last season then on the last day moving the boat for haul out, GPS wouldn't...
