I am looking for something beyond the manual recommendation because the manual is 13 years old and flush technology may have improved since then, and I asked for other people's experience. Nothing unusual in the drained coolant. Here's the Overheating Blues thread, but it isn't really a thread...

Thanks for the reply. Makes me feel better about the amount of AF I put in. I did drain from the exchangers, with the boat nose as high as the trailer jack will go. I noticed the drain plug isn't in the lowest corner of the exchangers and wondered how much difference that would make. I put the...

Macker29, I didn't buy the Interstates, they were in the boat when I got it. There is, however, an "Interstate All Battery Center" near me and I see there are a couple near Columbus, OH. I expect anyplace that sells Interstate should be able to get them.

Well, I don't have a Challenger, but maybe my Utopia is similar. The gauges and switches are all in a "binacle" that unfortunately goes around under the steering wheel shaft. I say "unfortunately" because if you want to get the whole cluster or binacle off you have to remove the steering...

I have two Interstate group 24M-XHD, 800CCA, 1000 cranking amps in my Utopia. They were at least 3 years old when I got the boat early this year and are still going strong. Are you using Marine batteries? They supposedly withstand the vibration and pounding better than auto batteries. I...

OK, this sounds, even to me, like a stupid question. I have a Utopia NA, twin 1503s (155hp). In the shop manual under Technical Specifications, Twin Engine Boats, Capacities, it says Engine cooling system "4.8 US quart total.' Not being used to working on baby engines, I assumed that meant 4.8...

I had a similar problem with my Utopia on one engine. Not exactly the same, but ... When you say "give it some throttle" do you mean move the shifter out of neutral, or move it until it would normally rev up the engine? Mine was a neutral starter switch issue, and as soon as you moved the...

Bret89, good idea to do your own maintenance but be careful of the exhaust cooling. You probably know this from watching the videos, but these boats don't use a jacketed exhaust manifold like many boats, the SeaDoo's cooling water goes into the manifold. So you can't just pump water or...

Related to my Overheating Blues thread, what do you all think the best cooling system flush is? The shop manual recommends "Valvoline Zerex Super Cleaner (or equivalent)" - anyone have experience with that product? I'm leaning toward Prestone Radiator Flush & Cleaner 'cause I found a 2019...

My boat has two batteries, sounds like yours had one, and the wiring diagram shows only one. Mine are wired in parallel, not one per engine. That probably explains why I have two different tie downs. The 2nd battery, left as you face the boat from the front (I'd call that the right or...

That stuff is happening in October? Yikes! I'm surprised that cover stayed on with what few straps I see, My trailer(able) cover that I think is original to my 2007 Utopia has like eight straps on each side that hold it down to the trailer, each with a pad at the cover where the strap attaches...

I've been reading the threads I found by searching for "Overheating," so I have a basic plan for diagnosing my 2007 Utopia 205 SE (NA) overheating problem. Runs fine cruising around the lake at plowing speeds forever, but after a few minutes of WOT, or more minutes of planing, I get the...

Damn, I wish you still had it! I've only had mine since March of this year and it's been a pain almost ever since. I just pulled the batteries out if it today, and I have two different hold down arrangements and I wondered which was original. Having another one to refer to would have been...

It's definitely a cable adjustment like gazzaskirepair says. A pain to do (at least on my Utopia, twin engine one control) and it's trial and error until you get the forward and reverse thrust balanced in "neutral." I'd forget the clutch idea.

Wow, another member with a 2007 Utopia! Great! I had that same issue. You need to devise some method that makes the front bolt clamp the hull - big washers or something like that. A mechanic who replaced my steering cable fixed mine, but I've had it off since then. Hard to get to to work on...
