Re: time for new manifolds

Go with the Osco brand..
When did Iboats start price matching??

Re: time for new manifolds

ok guys i pulled the risers. is there anything im loking for? any tell signs that they are shot.


Also could a shot impeller cause my manifolds to get hot?

Re: time for new manifolds

The impeller being "shot" might be responsible for clogging the system with remnants and there may be more than one impeller failure responsible.

The pieces of impeller can plug up the oil/power steering cooler and restrict coolant flow.

In much the same way riser/elbows (and manifolds for that matter) can do the same thing.

the result is the same. reduced net flow of water thru the engine can cause it to overheat.


If you haven't removed and inspected your raw water pump you haven't taken one of the very the first steps on this problem.

When manifolds and riser/elbows get corroded enough the flow of water thru will be severely restricted. The raw pump cannot pump enough water thru the engine to keep it cool if the manifolds and/or risers are restricting the flow...

i will change the impeller and see how that helps.

after i pulled one of the risers off, looking into the channels they seem pretty clear to me. not flaking with rust or severly corroded looking. sure a little rust but the walls seem thick.

Gary i too will recommend osco it's what i put on the boat when i needed a riser.

About the price matching it's what they posted in the chat forum, in a reply to my "Future of this site" thread.

Good to know Chief.....I missed that..Thanks..

Re: time for new manifolds

UPDATE:

i pulled a riser off to inspect. here is what it lt looks like. i know a picture tells a 1000 words, so please tell me what you guys see here.

Re: time for new manifolds

I see spots where it already looks like you have had blow by past the gasket (picture size isnt great but looks like nicks and rust trails across gasket seat). and as soon as you mentioned a cast metal part and jb weld I still say replace them both while you have them off. the guy that does it cheap is stuck in the middle of the bay waving his hands like a confused monkey.(i've towed that guy before)

You want to hear the bad news first, or the badder news first.

Heres the bad news first, that riser gonna leak on you and not to distant future.

Badder news, the other one look like that also ? Than that ones gonna leak on you ?

Still the same 500 dollars and a bargain to boot, if you get the WHOLE kit.

Gaskets, manifolds, and risers all in the same box at one low, low price.

And remember you want Osco.

Not GLM.

Do it right the first time you won't be sorry.

Good luck young man, i feel ya pain.

Thanks cheif. well the sad reality has sunk in. i will now be buying all new manifolds and risers

Re: time for new manifolds

Yeah, after seeing the pictures I agree. Get new risers, and OSCO's are good.

I still contend that if used risers are rodded out and pass a pressure test they will be fine for re-use. I've done it twice in the past without a problem.

Re: time for new manifolds

Arks was the ones you reused connected to manifolds that had freeze damage, and cracked and then JB welded.

The picks on this one tells the story.

No they were not.

ABSOLUTELY!
