Thanks for your reply. I used to work on radios and 20 years ago the ICOM's were the best for the money. Good to hear that they are still a quality unit. If I go away from Ray marine I loose the nmea but I don't even know what information is shared and if you need it or not?

My ray marine vhf has died and it appears to be too old to repair (12 yrs). I can buy the self contained unit for a third of the price of a new ray marine one. Just that I have to find a place to mount the new unit and then I have a dead speaker and handset from the old unit. Any ideas or...

I got earmuffs and set up a pump to recirculate cleaner through the drive. I had some West Marine scaling remover and ran that through overnight. Didn't see any effect. I then pushed fresh water and I also ran air backwards through the drive. It got better. I then got Barnacle Buster so I...

I didn't quite understand the hose on the inside of the transom collapsing? On the inside of my transom, I believe I just have the "blue" through hull connector where the bell housing hose comes in, then on the inside I have a 1.25 inch red hose that runs directly to the water pump. I can see...

I have twin Bravo 3's with 496's on a 390. I have low water flow coming into the water pump, maybe 30% of the other side. The entire transom and drive were new 4 years ago. I doubt, but maybe wrong, that it's the Bravo-itis. I can back flush the drive by forcing water back through the drive...

Since my boat are 496 gas engines, if we have water anywhere near the TVM, it means we are under water since our TVM's are nearly at the top on our engines. Sorry, I can't help but I did find a little information on this link: 3000 Series Zeus Pods Product Improvements (sbmar.com)

If you haven't yet decided on the diesels here is another reason. First my 8.1's are no longer made so if they go out your options are to rebuild the engine, buy a remanufactured engine or to repower to a newer model. Second issue is the cooling system, gas engines have a hybrid system where...

To follow up, I pulled the boat and the engine was fine, it was the new Bravo 3 outdrive. This one is going to be very interesting. There is a bolt missing on the upper cover. The drive won't even turn. It doesn't look like the bolt was ever there as the bottom paint is over the entire area...

I'm getting ready to pull the boat and the engine. I am looking at Michigan Motorz, Jasper and PPT for the long block replacement. Does anyone have any comments on these or someone else not mentioned? Most of the negative comments are in regards to warranty. Obviously I don't want to be...

I thought it was a little odd as well but when I disconnected the remote starter, the unit would not even turn over at the generator. I am sure there must be a mode that allows only the starter on the generator to run. I had read in another thread that either a shorted wire harness or a short...

Generator has always run fine and has 300 hrs and is about 10 yrs old. Just lately it would start and then stop. Thought I had just run it out of gas. All the maintenance had just been performed but I went through the gas lines all the way to testing the fuel pump. I took the pump off to...

Very good, thanks for the information. I didn't think about the fuel injectors. Also curious how many hours you had on the engine?

Thanks for the direct input. Just to clarify, you used a forklift to open and hold the engine hatch straight up without detaching it and then something else (lift truck?) to lift the engine out? Also curious why you replaced the fuel pump? The only thing not new on my engines are the fuel...

Yes, the outdrives were new 2 yrs ago and we had them off last year just to inspect but when we pull the boat and drop the outdrives we will check again before we pull the engine. I am considering doing this ourselves as "good" mechanics are 100 miles away.

I'm also looking for advice on replacing the long block by myself and a mechanic. My mechanic is a friend that has rebuilt engines from the ground up but out of trailered boats. It looks relatively straight forward but are there any gotcha's or tricks in pulling the 496's that require special...

First, the engines have been very well maintained. Fluids have always been kept up and oil changes every year etc. A mechanic already took a look at it and we can hear something metal in the oil pan as we turn over the crank by hand. It's either a rod or a bearing that let go and as you turn...

I've got a sundancer with mercruiser 496's, 2009 model year. Which by the way, I heard was the last year they were made. Something in the lower unit let go this weekend with 550 hrs on one engine. I'm trying to figure out the easiest and best way to get it repaired. Mercury only sells long...

Just to follow up on this post. Finally got the boat to Marinemax and the TVM alarms ended up being caused by a wiring harness intermittent.

Has anyone successfully repaired an acculift? I finally got one apart but now I'm searching for a source for the worm gears. Been through KHK and Boston gear with no luck.

Yes, I contacted Mercury and there are no "Seacore" manifolds or risors. Interesting, there should be. I ran the boat yesterday and temps were right on. Running nice and cool. Now I need to get the other engine done.
