manifold

I need a replacement for this manifold. 2002 30’ sundancer. Part number and vendor would be great. Or a totally different one that would pair up to existing plumbing would also be great. TIA.

I just bought a 1997 Sea Ray 175 3.0 merc Alpha One. I was just feeling how soft the water hoses were by squeezing them and the elbow at the pump crunched. I took it off and found this: Should I pull the manifold and other cooling parts clean or replace? Is this the manifold flaking...

I know there will be some strong opinions about the OEM version being the best. I would like to understand what makes the OEM so much better. My feedback request is specifically for the DRY JOINT version being it already is a better design to protect against water getting in to the exhaust...

I have been searching this forum and other internet sites and I can't find a definitive answer on how to flush the elbows (aka-risers) and manifolds on my 2005 Sea Ray 185 Sport (4.3l Alpha 1) while in the water and NOT using muffs. Biggest issue I believe is the Alpha 1 has the impeller in the...

I have rust at the manifold gasket, motors mounts and other part on and in the engine cabin. Any thoughts on the pics? 79 hours on the engine. Mercruiser 4.3MPI 250hp.

My boat is freshwater only, relatively low hours for an '87, and the manifold is a bit rusted and has been leaking slightly for a few years. Engine has been well maintained and running great. It seems to be cooling ok, though one side seems a bit hotter than the other. I've been afraid to try...

This is my story about having to replace not one or two engines, but now seven Mercruiser engines on my Sea Ray, and what I’ve learned along the way which will hopefully be helpful to you. First, you might initially think, judging by the sound of it, I’m into racing “go fast” boats that go...

New Sea Ray Owner. Just purchased a 2006 Sea Ray 250 Amberjack with a Merc-Cruiser 5.0L Engine. Boat has 150 hours and is in generally good running condition. Boat operates in salt water (Hawaii). (1) I was told that the manifold should be replaced every 3 years due to operating in a salt...

I tackled a project this week to repair some leaky remote oil tubes and seals (the ones in back, behind the engine). So I had to remove the exhaust manifold and riser just to access it. My question is: How much coolant should have come out when I opened the petcock on the bottom of the...

I am a first time posteR WITH A 2005 500DA, with QSM-11's. I recently have geen geting an alarm from the Smartcraft system when I click the engine switches to the "on" position. The error message is "155 ITM High". I know this error code is for the Intake Manifold. The temeperture readings for...
