also i was looking at cockpit carpet on corinthia website and they have something new called aquafelt backing material. just wondering if anyone has any experience with this backing product. thanks so much

Yes we are dealers for Infinity. Give me a buzz at the office and we can discuss it all. Also send me your info so that I have you in my database: https://www.covemarine.com (use the request form).

Thanks

Can anyone verify which of the two transducers the Smartcraft reads the water temp from? According to the Airmar site both are capable of reading the temp. My speed works and my depth works but the water temp reads -401. I have the following currently in the boat

Depth
Airmar 44-031-3-01
Sea Ray 888828-1

Speed
Airmar 31-407-1-41
Sea Ray 883090

Google search shows the depth transducer reads temp. Mine is bad and plan on replacing IN THE WATER within the few weeks. Being in MI I bet you are on the hard so I would do it before launch. Will share pics of the project once complete.

I replaced the depth transducer. I launch today so I will be able to see if that fixed the issue. It was on back order and not supposed to arrive until next week. I thought I was going to have to change in the water also. Please keep us updated how that goes.

I've got to do the same thing, I'm still trying to figure out how to crouch down between the transmissions and reach it with both hands.
 
electrical help needed.
Hi all hoping someone can point me a good direction. went to start boat for first time this year and it started up and idled perfectly. I noticed that stbd motor was reading battery voltage at the gauge on the helm and the gauge on the electric panel in the cabin and was not charging.

so I replace the alternator (old one was definitely shot) with a new OEM mercruiser alternator. now the boat wont start unless I push the emergency parallel switch. when I turn on the ignition i get nothing...zero volts on either gauge, batteries (brand new a week ago) test perfectly at 12.4 volts, I can start the engine by using the emergency parallel switch. once running voltage fluxuates from 14 to 15 volts (not good) otherwise it runs normally just having a charging issue.

I checked the ignition switches by swapping port for stbd and the problem did not move with the switch. I can't get any voltage to the ignition switch...I have battery voltage at the battery solenoid, and both batter switches.

where else can I check? I'm not getting voltage to my stbd ignition switch...is there a fuse somewhere for the ignition?

one other data point...I forgot to disconnect my batteries when I swapped out the alternator and accidentally touched the battery lead to the engine bracket and caused a spark...thinking this may have popped something but can't figure out what.

It must be self inflicted from me changing the alternator but just can't figure out what to look at

I was wondering about the 90 amp fuse...the starter works just fine when I emergency parallel the engines...would that fuse prevent voltage from reaching the ignition switch? I've got no STBD voltage at the helm, ignition switch red/purple wire or gauges or at the cabin STBD ignition switches or volt meter. I do have STBD voltage to the EIM systems, like the engine hatch openers and the helm electronics, GPS, etc. which run off of the STBD bank.

what path does voltage travel from the batteries to the ignition switch? I can't figure this out by looking at the schematics in the owners manual. looks like

I"ve got battery voltage at the alternator and at the battery solenoid, but not at the ignition switch.

Does anyone have the mercruiser engine wiring diagram for the starting / ignition circuits?

could the new alternator that has the fluctuating voltage be the cause of my issues? it's usually the last thing you touched that's the problem...in my case that would be the new alternator.

Does the wire on the back of the alt. that arced to the bracket still have power?
 
That’s a good question? I had assumed it did because I get alternator voltage at the gauge when the engine is running but I haven’t tested when it’s not running. I’m away from the boat now but I’ll test that tomorrow afternoon when I get back over to it. Thanks for the idea... keep em coming :)

There’s gotta be a blown fuse or tripped breaker. Test all the fuses or at least visual inspection of them and then maybe shut off every circuit breaker on the panel and turn them all back on. If that’s not it it would have to be an inline fuse somewhere similar to that 90amp one or perhaps a blown solenoid behind the breaker panel in the engine compartment. I think I have a pic of mine with the cover off I’ll see if I can see any fuses back there on the solenoids or something like that
