Marker One M27 taking on water

[Keowee_Ken]

Picked up a lightly used 2015 M27. Took it out for a couple of hours today. Towards the end I could tell we were sitting really low in the water, so it seemed we must’ve taken in some water. It was a beautiful sunny day, so nothing entering from above. Also, before leaving the cover of the dock for the first time in like a week, I turned on the bilge pump and only got a little bit of water out.

Once I turned on the bilge pump after being out on the lake for awhile, it was pumping for quite some time. Eventually I opened the ski locker and noticed it had a good bit of water in there even though the pump had been working for a while. Troubling.

Here’s the thing that I wondered as a first time Tritoon owner. If I did repeated backing maneuvers just practicing handling the boat, and never had the bilge pump on, could I have pushed a good bit of water up into the center toon? Should the bilge pump be left on on this boat? It didn’t seem like it was shutting off automatically the first time I drove it, so I thought maybe for some reason it’s not automatic.

Anyway, looking for any feedback that might help me not be concerned that there’s something more structurally problematic going on.

Hey KK. Welcome to the Cobaltchat forum. So glad you found us!

MNlakebumb has a Marker one and can chime in on your questions. Not owning a Tritoon myself, I’m not familiar with your challenge.

Do you have any pics?

Again welcome aboard mate!

Thanks! Unfortunately didn’t take any pics today. Just felt sluggish, and noticed stern seemingly plowing kinda deep in the water. Had taken on quite a bit of water, but bilge pump seemed to resolve for now.

I'm not going to much help as far as how/why you got water in your boat but I don't think it should take on water doing any maneuvers. But as far as the bilge pump, it should have turned on automatically. You shouldn't have to turn it on. I would start by looking at the float switch .

I would get that boat out of the water and give it a good examination...it shouldn’t have water

I didn't see this thread until now. The toons will not take on water during any ordinary maneuvers including backing up. I've only noticed my bilge pump run maybe a dozen times since I purchased my M27 but it stays in a covered slip and I don't get caught in the rain often. The bilge pump is automatic so you don't have to worry about leaving or turning it on.

Believe it or not when the dealer who stored it dropped mine in the water this year they forgot to put in the plug which I didn't discover until the next day. Luckily it was just the center toon plug and not all three as it was parked in the water for a few hours before I picked it up. Good luck with your M27 and I'm 100% sure you will love it. I put 100+ hours a year on mine and the only problem I've had was a leak in a power steering hose last Saturday which made it quite a challenge for my son to drive it home from the flotilla they were at 12 miles north of our home on the busiest boating day of the year, lol. The hose comes in by tomorrow so we'll have it back in the water within 48 hours. I couldn't resist reminding my wife "this is why we have two boats". We had 17 people at our home when the steering went out on Saturday so we put about 6 hours on the R5 on Sunday.

Pull it out and if there aren’t any obvious plugs missing you’ll need to pressure test the toons to see where it’s leaking. If you have access to shop air just bring the pressure up to 25psi and get a spray bottle with water/dish soap and start spraying until you see bubbles.
