    Any lower unit experts?

    Last oil change was at 1131 hours so I am going to say that was the first oil change had at least 100 hours on it. This year’s manager was very bad about letting me know things were due. He let a couple of boats go over 170 hours between oil changes and he wasn’t checking levels. I didn’t...

    Any lower unit experts?

    The engine is on a 23 foot tritoon and has about 1130 hours on it. The lower unit was changed because it was seriously damaged (skeg broken off, stainless steel prop nearly unrepairable on a severely bent shaft). I was told it hit a submerged tree at cruise power. I think the new lower unit has...

    Any lower unit experts?

    I just opened up the lower unit on a Suzuki DF200A and found a mess. The prop and housing appear undamaged and the prop shaft is straight. Any ideas why it would strip out like this? The lower unit was brand new last fall.

    V8-270-C-B Exhaust bellows (hose) replacement

    Thank you, I ordered the book through them so I hope that part of the system is working.

    V8-270-C-B Exhaust bellows (hose) replacement

    I can’t seem to find any information on the internet to confirm which manual I need for the exhaust system. Even the Volvo Penta website now says no products available or only shows a fraction of the documents it did for a V8-270-C-B. I see exhaust manuals on eBay but of differing part numbers...

    V8-270-C-B Exhaust bellows (hose) replacement

    I understand supplements. My experience is that they get added to the existing manual instead of getting published and sold separately but these boats are the newest things I work on so my experience is probably outdated. My beef with Volvo Penta isn’t so much the multiple books as it is the way...

    V8-270-C-B Exhaust bellows (hose) replacement

    I wish I knew the serial number. The tag on the cover is all but blank. It looks like some kind of cleaner or solvent got on it. I encountered one a while back that was missing the cover and was able to call Cobalt to get the serial number. I need to call them one of these days and do the same...

    V8-270-C-B Exhaust bellows (hose) replacement

    Now that the elbow is out… maybe I should crawl back in there and check the manifold gasket in that area….

    V8-270-C-B Exhaust bellows (hose) replacement

    I pulled the elbow. The bellows is soot covered as can be seen in the photo. It is also soft and pliable. Looks worse out of the boat. Cannot find a hole but no evidence of it leaking around the ends either. I have a pretty good collection of manuals from Volvo. None of them talk about the...

    V8-270-C-B Exhaust bellows (hose) replacement

    What about torque values on the bolts and nuts? It’s pretty standard for me to use an X pattern when tightening things but it would also be good to know if there is a specific sequence to follow. I don’t want to replace a bellows just to start a leak at the catalytic converter by doing shade...

    V8-270-C-B Exhaust bellows (hose) replacement

    I have a leaking exhaust bellows between the left elbow and the Y-pipe. A local shop recommended changing it but didn't offer any tips on how. I slid the bellows down the Y-pipe thinking there may be a gap to work it off the pipe and install a new one but there only appears to be a 1/2 inch or...

    Engine alarm won’t stop

    I can’t believe how hard it is to get parts these days. If it’s not back ordered, it gets lost in shipping.

    Engine alarm won’t stop

    Ran the boat today with a new trim position sensor installed. The alarm didn’t sound once while it was running. Can’t put it on the lake yet because I lost the grommet clip. I spent a couple of hours with a magnet and a borescope to no avail. I think the designers intended the engine to be...

    Alarm won't turn off Volvo 4.3gxi

    I had a trim position sensor causing an alarm. Disconnecting the sensor didn’t silence it. It beeped every 7 seconds until I changed the sensor. Ran for 10 minutes today in the tank with no alarms.

    Engine alarm won’t stop

    I unplugged the trim position connector and kept getting the scan code but the boat wasn't beeping... for about 5 minutes then it started beeping again. Once about every 7 seconds (counted, not timed) and a new code appeared on the scanner... 924 indmar cam phazer(?). I don't see SPN-924 in the...

    Suzuki lower units

    Is there an alternate source for Suzuki lower units? I ordered one 5 weeks ago that FedEx or one their contractors appears to have lost. Can’t pay another $3800 even if Suzuki has gotten another in stock. Mercury, Yamaha and OEM can be sourced through SEI but I haven’t come across anything for...

    Engine alarm won’t stop

    I didn’t get a chance to work on it today. I spent the morning studying the manuals I could find. I had to babysit the grand-babies this afternoon. At this point I pretty much assume I need a trim position sensor but there is no way to get one before the weekend. I won’t actually order one...

    Engine alarm won’t stop

    I finally got the engine running again. Had to pull spark plugs and locate TDC for the #1 cylinder. The distributor was 180 degrees out. Beeping frequency changed but did not go away. I couldn't get the local Volvo Penta shop to take a couple of minutes to hook up a code reader once all summer...

    Do you use Loctite on your lower unit bolts?

    My experience with red loctite is that it isn’t uncommon for it to take heat, as in torch, to break it loose so I am with you on your choice not to use it. I wonder if that parts manual has a misprint. It would be nice to hear from a certified Mercury mechanic on this.

    Do you use Loctite on your lower unit bolts?

    What does the manual actually say? I don’t have a Mercury manual but I know the Suzuki manual calls for thread sealer instead of thread locker in those places. Fairly certain Yamaha does too. The only “certified” boat mechanic I watched do an impeller didn’t put anything on the threads.
