Merc Black Max! HELP

[NorwegianBoater]

Ill check on the reeds this weekend. I dont run a stat in my motor, I have a pressure guage and I get pressure right off idle as well as a pump that is only 1 season old. It probably would be a good and nice idea if you started your own thread with these ideas and suggestions in it. It could be really helpful.
Yeah that would be great! With pix and etc. of the third water hole
Thanks!

Arrows show where the holes are.
Most older 2.4 L Mercs. have only 2 holes here. I drill an extra one at all 4
spots in the block. Take care not to drill thru to the outside or you will have
a leak. If this happens, you can build up some JB Weld to stop it, but we
would rather not have this! Also, the water diverters to route the water
the long way around the cylinders. These are regular 1/4" ID rubber fuel line
pieces cut to fit. Leave an 1/8" open at top and bottom (eliminates stagnant
water)
Good luck!
