225VRS loss of power question

I fired up the MC yesterday for the first time this year. I decided to make a long run up the lake and back (about 50 miles) to see if anything was going to misfire / break on the test run. I did not have any problems on the way up. But, coming back, I had it in the wind and running about 4500rpm (45mph) and the engine made a tone adjustment and the speed went down by about 4-5 mph. It felt like I lost some of the power. After throttling down and then back up it was fine.....but did it again later.

I was thinking that it could be the thermostat stuck open. My guage reads 125 degrees continiously. I was thinking that it shoudl be in the 140-150 range.

Any thoughts on this?

Take a look at the fuel filters...I had a similar problem ans it turned out to be stuff stuck on the intake screen of the fuel pump.

Probably what Jorski said, some restriction in the fuel path that "caught up" to sufficient fuel again when you throttled down.
You should be in the 160 deg range for water temps, maybe thermostat stuck open??

97 Maristar 225

I have a 1997 225, I was wondering how may hours and what if any problems you have had with yours. I have around 350 hrs and only minor problems such as the altenator bracket, belt, seat skins, etc. Mine looks like new, has been garaged all it's life, I added a tower stereo and it all works fine. But I'm considering a new or new model X Star. Not sure what I can expect in the way of problems with the age of my boat. What kind of history have you had? Your comments are appreciated.

I actually cant give you ANY advice.

I bought mine last year (1995 VRS 225) with 14 hours on it. Some super wealthy fellow bought it to run on his private lake. It was always garaged and was as good as new when I got it. Dealer stood behind it and had all of the service and winterization logs. I got it for a good price and have loved everything about it.

If I were trading up, I would not focus on the x-series. I would go get a 230 Maristar and add a tower and ballast. Have you seen one done this way? Baddest boats that I see around and it has the luxury feel of a nice car.

Sorry that I can not help you. But, anything that you can tell me about yours is greatly appreciated!

Matt; That is a lot of sitting, 95 with 14 hours! Clearly not good for the engine to run that cold, first problem to attack. Could be a partial fuel blockage or weak fuel pump. If it only did this twice in 100 miles, I would be tempted to keep running, could be lumps of gas going through.

Congrats on the NEW boat!

Matt,

One or two suggestions. Make sure you keep a conditioner on the seats after cleaning as they will drt out anc crack in the seams if you do not. If you do not have a brand I can makea recomendation or my buddy uses a product called 309.
Do you have a tower? Do you paln to put one on? If so, let me know. I can send you photos of mine, It looks great, but it's not the most sturdy one I've seen. Of course I also hand an airchair, boards, etc on it.

I have had the boat for a year and do have a tower. Monster tower to be exact...best around for the buck.

I will start taking better care of my vinyl and plan on conditioning it this year.

Last year was all about learning...
I learned that vinyl will tear after placing a wakeboard fin on it.
I learned that when coming off plane when the tank is low....you are truly out of gas.
I learned rocks and stumps bend props, but they can be easily fixed.
I learned....when out by yourself dont freak out if your boat wont start...put the kill switch back on and look around to see if anyone saw you freaking out.
I learned plugs are a good thing, and a buddy with good ears is also a good person to have pulling the trailer back up the ramp.
I learned that if water is coming in the boat fast...its the exaust hose that slipped off.

Yeah....2004 is all about learning. 2005 is all about learning inverts.

This could be your problem.. Running out of gas can damage or ruin your fuel pump.. ( I think mine is bad) Do a fuel pressure test....

And leaving wet towels on your sun pad will stain lighter colored vinyl...

I only ran out one time.....It was right at the marina, and didnt try to turn it over anymore. That was the same month that I bought it...and I didnt have any problems until about the end of the season...

I am thinking its the fuel filter.

Thanks for the vinyl warning though....Thats all I need!
