Picked my boat up on Thursday, took it out and have about an 1 1/2 hours on it . Two issues, one the engine doesn't appear to heat up past 135 degrees and lot's of water in the bilge. I can't see where the water could be coming in from? Drive shaft seal maybe? But I thought it was dripless? And I beleive the temp issue is the thermostat as the heater isn't that warm either. I know I should just run it back to the dealer, but at over a 120 mile round trip it's cheaper to fix myself then pay the gas to get it there.
Any one else encounter either of these issues on their new rig. Other than that, once broken in this is going to be great!!
Water in the bilge - I know this sounds way too obvious but have you checked the drain plug? It may not be tight.
Cold is better than warm. But it is tough to break in a cold motor. My problem went the other way. My first thermostat ran hotter than normal.Originally Posted by h2oskierrick
Couple bolts, replaced.
I had an issue with water in my bilge, turned out I had to change out the shaft packing.....made a huge difference
Hoses are not clamp down.
The 07's were supposed to have a dripless seal? Which it does have, just not sure if it's working. I checked all of the clamps and hoses, nothing obvious. I'll have to throw it in the lake to see if I can spot where the water is coming in, and yes, ... the plug was in. Not that I hadn't left it out in the past on my other boat !Originally Posted by deepcove
I think everyone does that once!!
Hopefully I can see it when I get it back in the water.
The thermostat I just going to change out and see what happens.
Thanks for the input everyone!
Where are you guys getting your thermostats? Is it a standard one or is the Indmar thermostat different than the standard ones? What was the part number. Thanks.

as for the water in bilge put it on trailor (drain-plug in)put water hose in bilge partial fill then start looking for water leaving boat! lot easier to find a leak this way than in the water![]()
I did pick up a thermostat today to put in, my marine shop couldn't find the reference for the Indmar. The good news is when I pulled the original thermostat it was only stuck open with some gasket or sealant material. I was just going to throw in the one I just bought, except when I compared the two the newest one didn't look like it would flow the same. The opening seemed to be only wo thirds what the factory Indmar was. So I cleaned and tested the original and it works great.Originally Posted by Buttafewcoe
I also found my leak, the water strainer for the gravity tank was leaking. I do have a new issue though, the gravity tank fills while I am under way even with the switch off? It's like the solenoid witch never closes. Getting closer to being broken in, can't wait to ski!
Thanks again for everyones input!
Oh yeah the Indmar Thermostat PN# is 985009
The Sierra PN# for 5.7? 160 degree thermostat is 18-3649
