After waiting 7 months to take my 2001, 24 Pantera (496 HO MAG) out, I finally did today. I went approximately 1/2 mile and noticed a smell a rubber burning . I opened my engine hatch and notice a minor water spray and exhaust blowing out of a 2" hole in the 4" diameter rubber exhaust hose that leads from my exhaust manifold to the through-hull exhaust. I checked my guages prior to this,and noticed that my temp. gauge was reading about 165-170. Is this normal operating temp? I also checked at start up to make sure that water was blowing out the exhaust and also after I discovered the hole in exhaust. Should these 4" rubber exhaust hoses be changed often? Thanks Jeff

No they shouldn't. Also that is a tell tale sign that you weren't flowing water.
Were you seeing water through the exhaust after this happened? 165-170 after 1/2 mile seems on the high side. Perhaps something clogged the water pick up. Happens here all the time due to sea weed. I usually see the temps start heading up so I stop go in reverse a few feet and then see the needle drop down.
I would do a thorough check and see what the problem is. At 170 you should be fine as far as not hurting the engine.

Wildthing,
Dropped the boat off at marina and their first impulse is to check the impeller. I will keep you posted. Thanks Jeff

The 496HO has a safety defense system built into it.
If it gets too hot it goes into a safe mode and won't run very
well until it is cooled back down.

These are closed - cooling and do run 160+. I think the T-Stats are 160.
