mercruiser 454

Alright I am going to start from the beginning because I am a total novice and need all the guidance I can get from you wise gentlemen on the forums. I'm gonna swallow my pride and be totally honest with all my boneheaded mistakes. I live down in San Diego and bought my first boat, a 1993...

I need new risers on my 7.4L Mercruisers and I found used stainless steel mercruiser risers for sale for cheaper than the new Barr cast risers. I would imagine this would be the best way to go since the rest of the engines are FWC and with stainless risers, in theory I would never have to touch...

Hi. I have a 275 Sundancer from 1999 with a Mercruiser 7.4L that has been salt water cooled. I am presuming the corrosion is soon tearing the block apart and am looking at replacing the block. Can I replace the 454 block with a 496 or other and use the same components or will the components not...

Hey guys, I relatively green as far as maintenance on my boat goes, but not totally ignorant to basic mechanics. Here's what I'm seeing... Coming in this weekend I was pushing a lot of steam of both exhausts. I immediately checked the strainers and no blockage/excess debris (tho port did have...

I've sold my boat so I am selling off various items that I have left behind. It was a great boat but now she is gone and I have no use for this ladder so I've listed it for sale: http://www.ebay.com/itm/190714867768?item=190714867768&viewitem=&vxp=mtr I am also listing a few replacement parts...

Hello to all Sedan Bridge owners! I have not observed (or could not find in a search) any threads for discussion concerning the 370 Sedan Bridge. The 370 SDB has great lines and reflects all that is good in Sea Ray design. I have a 1996 model that recently took a trip from North River, Lake...

Tried to start my starboard engine (inboard Mercruiser 454, 7.4L, Thunderbolt)couple of weekends ago and couldn't get it to fire. Seemed like the starter was giving it juice, but couldn't get anything but a few little "pops" out her. I replaced all the plugs today, and nothing changed. Does...

Port engine (Mercruiser 454) purrs like a kitten when not in gear. But, when the transmission is engaged it knocks like crazy at idle speed. Seems fine at higher velocity, though. At first I thought maybe this darn E10 gas had fauled my carburator. I have a 1990 Sea Ray Sundancer 350, so have...

Hey Team: I'm biting the bullet and re-powering my '98 454 to a Merc 496. (I'll just say water in the manifolds and move on....) Has any one done this? Any gotchas I should be aware of? I'm thinking something just isn't going to line up right.... Any "heads up" is greatly...
