The X-900 is "NLA" and BassPro does not provide battery specs for this new one in the description. :rolleyes:

I blew the gp31 pic up and the label says 772 or 773 CCA so that doesn't meet minimum...

VesselView is accurate, and that's low, you should be seeing 13.8v minimum at idle.

+1. Once the poppet opens the stats no longer control engine temp, this is why it's critical engine coolant temp reach at least 120° prior to accelerating.

Screen is probably clogged with bits of liner, if you've never replaced the pulse pump, now would be a good time to do so.

One commonality among the many recent posts on this also includes a deck fill.

Could be the neutral safety switch in the shifter. Next time it happens try jiggling the shifter handle fore and aft a little, if you can get it to start that way replace the switch.

Telltale on an Optimax is the compressor cooling outlet only. At this point, your best course of action is to have the codes read.

There are many things that can cause a 6 beep alarm, only way to know is to have codes read.

Think I still have one after going to the Smartcraft float assy will check when I get home this afternoon.

Yes, the only difference is the labeling and where they are sold - Mercury label from Mercury authorized outlets only, Quicksilver (same exact oil) sold at non-Mercury outlets, Bass Pro, WalMart,...

Yessir.

Primary reason why I watch my thermostats cycle twice before accelerating gradually on every cold start. :wink:

My pleasure! Since I don't have any helpers, when it comes to stabbing the lower unit, I want it to be one and done. :wink:

I don't know but that's amazingly clean for a '96! :thumb up2:

As Savage said, engine cooling system is only under thermostatic control when the poppet is closed. Once the poppet opens thermostats are, as Don says, just along for the ride. This is why you should...

Primary contributor to your problem, an Optimax runs "dirtiest" at idle speeds and WOT.

No.

If you put engine into neutral prior to disassembly, did not touch shift handle or shift shaft while servicing water pump, it will be correctly lined up. Marking the driveshaft is so you don't have...

Yep. :yesnod:

Correct, I've never seen less than 13.8vdc at idle even upon initial startup.

Idle a lot? What rpm do you run most of the time? IZFR5G is the most current and correct spark plug for your engine but you'll probably be fine with the platinums. Make sure you follow the plug...

You need to spin the prop by hand when attempting to shift into F or R with the engine off. The prop will be locked when in gear. There are square cut teeth on the clutch dogs, if they're not...

^^^^^ and, if properly configured, your engine should indeed show water pressure via Smartcraft.

I'm not familiar with the 1.5L Optimax, but, there has to be an air inlet for the compressor and that's where you would add PP to it.

Topwater last logged on a year ago today so not likely he'll respond. The BEST course is to open a topic for your engine, with serial number, and describe your issue. Note, also, there is a one...

FYI spark plug service interval is 100hrs or annual whichever comes first.

Using a deck fill for your remote tank?
