I am not oppsed to water pumps and such but I don't have them parts I never did, these crossovers been on my boat way before I owned it...

If I can locate and have funds I would get them, but as inkjow it's a better way it's also not the only way to keep this alive, just loosening the guides and lifter bores will fix my issue alone, I think everyone can agree on that.

Kinda like when I had oiling issues 8 years ago.... Everyone here said it was my filter and it was not even close to the issue.... I love advice and listen to everyone but at the same time if I changed weekly what everyone said to I would never boat, i do appreciate the help and again I listen, mike T and I talked for half hour yesterday about my issues and ideas so if it seems I don't listen.... I do

I am guessing it's a cost thing?

When fixing engines and in June yes it's a cost thing... I am willing to spend what's availible and I did all winter I'm tapped guys, I will not miss a season that's just how I am, I will fix this and it will be ok I am sure I know where the 2 main causes are and I am addressig it

Tim, I have a circulating pump I would donate to the cause to help a brother out. It has a flat pulley on it from serpentine setup. Im pretty sure (not positive) you can put a vbelt on it and spin the other direction. I have to dig it out of my junk pile (shed) pretty sure I have a thermostat housing (if I didn't give it away) let me know what you want to do. I'm sure the pump would last you a few seasons.

Thx let me see what I decide there really is no reason this setup of over 20 years won't work to be honest...it's not like I just did this

I switched to the thermostat style crossover necks from the non thermostat style and they seem to work ok.

I have a 2 v belt pulley for the water pump if you need it Tim.

Tim, I was just looking at a photo of your engines. Have you considered simply installing a thermostat, with a bypass hose on your setup? Since you have the bypass's already. Make sure you get the high flow robert shaw style stats with the holes in them already.

My buddy bill was saying same thing, that's probably what I will do for now, you of all people know how much money I got to fix the actual issue here...

Ifyou are not already - check your water psi !

ok...seems your splitting the water at the cross over you start with splitting the water from the sea pump.tp the bottom of your exhaust manifolds..out the top from where it connects to the riser..from that part of the manifold to the front of the block..out the thermostat housing to the risers..that is good gor 40* with a restrictor plate which i know your not running...you have have some resistance there or the water is just going to run through the front of the block and the rear of the engine will get to over 200*
