The track is screwed in to the fiberglass below it. Try checking to see that the mounting screws are all tight and not protruding up into the track. It sounds to me like a loose mounting screw may be chewing up the truck as it rolls across a screw in the track.

Checked the screws and all appear tight. The track does look a bit chewed up possibly explaining why the truck keeps jumping out and destroying itself. The lubrication did make a 60-70% improvement. I may buy another truck and re-lubricate. Long term I should replace the track. Thanks again for the feedback.

I use a whole house filter (spin on with cartridge) at my dock and when I travel I use the Camco RV inlines (which get replaced each year - I buy the multipacks). Been doing this for years to prevent "junk" getting into our fresh water systems. I also work off tank water for our day to day use to keep them flushing through (unless I am at dock and want the water pressure to shower). I try my best to keep our tank and lines in great shape. Years ago a friend told be about horror stories about clogs in his lines due to sediment.

OnTheJob, this weekend I added an inline RV filter like Kevin mentioned. $22 at Menards and only took 2 min to hookup. I flushed and refilled my holding tank with filtered water. Noticed most of the houseboats at my marina use the same setup.

That track is ready to be replaced.
 
Anyone have water accumulating in the forward floor compartment? It seems to be a sealed compartment but somehow I get water in there. Would like to use it for storage but I don’t trust it won’t get wet

If your referring to the compartment just forward of the shower bilge compartment, then what you’re experiencing is excess condensation from your air conditioner (under your forward bed) draining into that compartment. I experience this when it’s hot and humid outside. There is probably not a leak in your AC condensate pan and it’s probably not overflowing due to a clogged condensate drain line; if it’s the same as in my case, it’s simply excess condensation on the exterior of the pan and components. I use a shop vac to remove the water every few days so I don’t get mildew issues.

I just went through a whole leak issue. Please take pictures of where the water is coming from and, also, taste it if you can to determine salt vs fresh if you’re a salt water boat. I had water come in through the hatch, skylight, port light, nav light and bow rail. Chased each one separately. I feel your pain.

Oh wow brutal. I have a water stain on my front port side speaker cover so I know I have a small leak up there somewhere

Are you talking about the one by the front bed or the one over the galley?

If the one over the galley pull the speaker and the port light ring and take a look. The headliner is simple plywood and is not protected from the elements since it is an internal structure. If there is a leak the wood will get wet and eventually rot even worse it could be dispersing water elsewhere.

My small round port light above the galley sink was leaking this weekend so I had to pull the port light ring and I had to rebed it this morning. Found it while I was washer her down and wife told me it was dripping. It was a small leak but I hope the seal cured in time for tonight's rain.

It was probably do to the excess heat on bearing down on the deck and then slamming her into a sandbar :( Not a good weekend ending for boating but the rest was great and BoatUS made out well. I heard of several boats getting grounded in the late afternoon low tide. At least I made it home with out needing a tow after getting off the grounding.

Font sole storage should be dry. As mentioned look at your AC unit and see if it was overflowing - should be easy to get a visual on. I know my sump pump was running alot due to the condensate.

I hope its all better now - except for that zipper ;)

This is my setup. Culligan water filter that’s clear so u can see the filters. It’s pip thread so u just need the pipe thread to hose thread adapters at both ends.

Oh my what a sad, expensive Spring/Summer. Easter weekend greeted me with discovery of significant water in the port engine while checking oil. Ended up pulling heads, doing complete valve job on both heads, new manifolds and risers. Work was done by a mechanic I found a while back who had helped me with routine maintenance. Heads were very, very rusty and were somewhat expensive to have reconditioned. At the end of the day, cost was about $7k. She ran great for the next three weekends. Then we took a trip to Bimini. About 8 miles off Bimini, starboard engine blew. Engine was running proper temp and oil pressure. No alarms, just running at 3400 rpms and BOOM. Hauled her out, pulled the engine and disassembled. Found that the number 7 piston had melted. Seems that is not as unusual as I would have thought when I googled it. The disintegration of the piston destroyed the block, cam shaft, lifters, etc. Major sadness. With funds being limited, I went the long block route. Also had to get new oil cooler, replaced the gen 3 fuel module. Also new risers and manifolds. Topped off with servicing all injectors. All in...another $11k. Up side is pretty solid power in the boat now. Down side is no vacation this year....
 
Wow that sucks!
What motors? 8.1 Horizons?
Any idea what caused your heads to get so rusty and ingest water?
 
Yes, 8.1s. Not water that caused the problem. My guess is no gas in that cylinder causing it to superheat. The heads on that engine were in great shape. So much so I am hanging on to them, since they are 1500 each.

Wow that really sucks. I am having a little problem following along in the diagnosis though. You said water did cause a problem yet you said the heads were incredibly rusty. Also how would no gas cause the piston to overheat? Wouldn't that come from a too rich mixture or blockage in exhaust port? Without combustion the engine should loose power but not melt the piston.

Ahh, ok. To clarify, the rusty (had to cut the heads of the bolts off with a Dremel to remove) heads were on the port engine. Obviously had some water issues at some point before I was the responsible party. The starboard engine, which had the piston issue, had no issues with the heads at all. They were in great shape, as was the other 7 pistons. since all else was in such good shape, lack of fuel to the one piston is all we could surmise given the lack of alarms, etc. I am not sure if, when running on plane for the more than two hour trip over to Bimini, I would have been able to detect one cylinder dropping out.

I would think you'd have to give the Starboard engine more throttle than Port to match their RPMs. Do you remember if your throttles were uneven during your trip?
