Last weekend outing for blown 2002 225HO Ficht Engine - Should I disconnect plugs?

I blew my engine 2 weeks ago... old 2002 225HO Ficht.   Cylinder 6 with 0 compression and 0 reading on leak down test.. don't really know what that means.  And cylinder 5 very low compression ( 45 ) but still moving.

 

I need to get through a small club tournament this weekend with the engine, before I take off the engine and repower over the winter.

 

The engine *does* idle/run and that is all i want to do for my fishing outing this weekend... just have the ability to idle, even if alarms are going off Smiley Happy

 

Would it be safer to disconnect spark plug wires 5 and 6 so that those 2 cylinders do not spark ?  Will that cause the 2 injectors to stop flowing fuel into those 2 cylinders ?

 

I'm thinking it is safer to idle with 4 plugs connected ( the good cylinders ) and the 2 bad ones disconnected.


Does anyone know what is best for me ?  Fishing in a very small safe river and I have a trolling motor..... not going out into any unsafe territories.... i just want to idle without blowing up Smiley Happy

 

Thanks!

Probably not possible. The pistons on cyl 5 &6 are probably gonna Come apart at some point during your trip. Then a rod through the block, etc.....

Not recommended.

Removing the plug wire will make no difference. The fuel injectors will still spray fuel.
With 0 and 45 lbs compression the fuel will not ignight so you will have unburned fuel going into your crankcase.
