temp gauge never gets very high...thermostat?

[tlatoani]

Hi guys, I have an 05 XLV. The temp gauge never seems to get above the second notch (the first being the far left one). I can't remember the numbers, but it may stop around 160ish. I am pretty sure this is not warm enough. Am I wrong, or does this mean a bad thermostat? It seems like the gauge actually does work since it moves a bit. Is a thermostat tough to replace?
thanks

I have an '07 LSV with a 180 degree T-stat. My temp gauge bounces between 180 and 165 which means the T-stat is working properly. I was told that prior to 2007, they used 160 degree T-stats. If that's the case, then yours sounds like it's working just fine.

I have 06 LSV w/ 325hp Fuel Inj and it runs between 165 and 180..mostly around 175. I had 04 Outback before with 310 Carb and it hung around 160-165...

I thought the 160 that I mentioned earlier sounded funny, so I stopped by the storage unit to double check. It's going to ~135. Something must be wrong, right? It seems to run ok to me.

Mine does not get above 110 so I am even worse off.

The boat is only 1 day old so is there a break-in period?

I can confirm the older carbed 310 goes from 160-165 and stays right there.

this time of year (in Central Florida), with the temps in the 90's and water temps almost that warm, my 2003 with the carbed 350 engine normally runs around 180 degrees.

I got mine up to 130 today.

I think the reason why I cant get it to normal operating temp is because I am taking it easy durring my break-in period and the water is VERY cold.

All current Indmar engines use 160 degree thermostats. Current Moombas have a separate temp sender for the gauge on the dash and for the ECM so it is possible that what you are seeing is a gauge or sender malfunction.The only real way to tell is to shoot the thermostat housing eith an infra red thermometer or hook the engine up to a scan tool and see what temp the ECM is reading from the coolant sensor. With a 160 stat, the engine shold run at least very close to 160 and depending on the water temp might go as high as 190
