The engine is a Mercruiser 300HP 6.2 liter. 2017 220s is the boat

On the water I have never noticed it get higher than 140 I don’t think it seems to run really cool. I’ll try it out tomorrow and report back I guess I was more worried about having hurt the water pump or something like that when running the muffs on it.

Hello, I recently ran my boat on muffs in from of my house, I verified they were on correct and that the lower unit was down. It seemed to climb in temp pretty quickly it hit 158 degrees in a few minutes, anyone out there know if this is normal? I’ve never seen the temp that high to my knowledge ...

Ah great question, but I have no idea lol.

Thanks for the response I live 2 hours from the dealer so it turns into a whole thing lol

I have a 2017 220s with a Mercruiser 6.2 (300HP) and while at the lake today my service soon indicator came on, I am wondering maybe if I have bad fuel?? No alarms or horns heard just the indicator.

Oh man!! That’s rough sorry to hear. I think I’ll look into some new ones I guess!

Hello all, I have a 2017 220s, my dealer just informed me that it needed jumped before they could perform the annual maintenance today, what is the typical battery life for a boat? I really don’t think I drain the batteries that much or at all throughout the year, certainly not as much as others do ...

Thank you all for the response!! I will look that part up and get it ordered. Thanks again!!! As requested I have attached a picture of the boat.

Hello all, I have a 2017 220s that is “Sirius ready” can anyone tell me what it takes to get the Sirius working? It just tells me to check receiver.
Thanks,
