My exhaust elbow was completely rusted. (scroll to top of this thread for picture) I replaced manifolds, risers, elbows, thermostat, removed raw pump and visually inspected impeller. Engine overheats at cruising rpms. Found one chunk of rusted metal wedged in upper exhaust tube. Maybe...
Finally took the elbow off again, and the flex exhaust tubing. I see a hard oval tube in the bottom behind the motor. It has some kind of rod going through the middle and some deformed rubber thing straddling the rod. Must be the flappers. I can't tell but can this (Y-pipe?) be removed from...
Yes, I may have hijacked the post which was about rusted risers. My posts here progressed from changing the manifolds, risers, and elbows, to "why is it still overheating?" To your question, yes I chiseled the pieces out of the rubberized exhaust connector that the elbow attaches to. And no I...
Impeller was in pieces, and yes I got them. I found the broke pieces in the pump outlet hoses and re-assembled the old impeller to verify that I had them all.
Not sure where the water comes in. Per the mercury parts catalog for my S/N it comes in thru a transom hose. I will go look to verify...
Update: So I got my engine running. Still have the initial problem of overheating though. I had changed the manifolds, risers, and elbows. I made sure the orifices were lined up as on the original manifolds and risers. Still over heating. Then I pulled the raw water pump, even though I had...
Ok, I'm on my own. Got to do this myself then, fine. So there was a link once with detailed instructions call Porthole leak how to fix. From 2012 or so. But that link is dead now.
Can someone re-post it?
Well I just dodged the mother of all bullets. You know that feeling in the pit of your stomach when you think your motor is shot? I had that since my last post above.
So I sprayed SeaFoam brand Deep Creep penetrating lubricant (no, not the gas treatment - different product) into my spark...
So I just replaced exhaust manifolds, 3" risers, elbows. It sat for a week with the parts removed, and boat is on a lift. I'm saying this because now it wont crank. Engine turned a few degrees then stopped. Batteries fully charged. Seems like water-lock to me. How would water get into the...
That's bad but mine were worse. Check this out, the tip of the elbow broke off and was lodged in the exhaust tube. Needed a chisel and hammer to dislodge it. I had the boat for 3 years so who knows how long it was like this.
Yes I know, Im responding to an 8 year old post. But this helped me alot. Changing the elbows, risers, manifolds on my boat right now. I had that same stuck elbow fitting on the manifold bottom. What baffled me was the replacement manifolds (Sierra) came with a different style elbow with the...
I did this in 2014 for all the DC lights in the cabin. Bought the adapter base and bulbs from Amazon.

My '98 has the rail and ledge. The ledge is so narrow, it's barely as wide as my foot so trying to walk along that is like just asking to fall off the boat. I always use the windshield to get to the bow and anchor.
I have a 98 250 and mine leak too. I have needed to replace them for 3 years now but havent found anyone to do it. I wont do it myself. I removed and re-sealed the top square porthole, installed new arms (previous broke) but the damn thing leaks. So I suck at that kind of work and will not...
Snap Straps - So there's a small ankle high door on the back of the boat leading to the swim platform. You can secure it open with an attached snap strap. But - Oops it just ripped in half last weekend when my daughter pulled on it too hard. OK the thing was deteriorated. It's a '98 after all...
