New to this wonderful forum.
Boat Info:
Sunchaser 1901 XL Deck/Bowrunner Model
Alpha one O/D
Engine Info:
Mercury Marine
Model: MCM 5.0 Litre/LX
Displacement: 305 CID (Cubic Inch Displacement)
Rated HP: 230
Ignition Timing: 8 BTDC (Before Top Dead Center)
Cylinder Firing Order: 1-8-4-3-6-5-7-2
Spark Plugs: AC-Delco MR44T
Engine Rotation: LH (Left Hand)
Max WOT (Wide Open Throttle) RPM: 4200-4600
Spark Plug Gap: 0.035
Hours: 715
So with the brand new battery I recently bought, she starts up great. Get out in the water and can idle around or go all out 50 mph and we have no issues. The problems come after cruising around for an hour or two (or 6) we decide we wanna find a nice cove for swimming and turn off the boat for an hour. We don't use any electronics while stopped. When we decide we want to get back to skiing, she starts back up a little slow but will start. We'll get about 5 minutes in and it'll die. Doesn't matter if we're going no-wake speed or fast...the engine will just stop. We can get it started another time or two but finally it becomes unstartable.
We've had the issue probably the past 5 times we've been out. Only happens on the restart after the hourish swim. Aighnt a big deal because we'll just have our jetski tow us in...but it's getting old.
Every time we go out, we change a little something. Things we've tried:
-Added two blowers for more air flow
-Changed out gas
-Only use high octane fuel
-Cleaned carb
-Allow it to warm up before beginning again
-Try traveling fast and slow
-Used Seafoam to clean things out
-Check for negative pressure in gas tank
Out of ideas because it's difficult to test when it starts and runs great the first run of the day.
Any suggestions would be greatly appreciated.
