The stock Merc cast iron exhaust manifolds - any ballpark figure on how long they last in freshwater? I have a 1990 Sea Ray 220 Cuddy with the 260hp merc and just under 400hrs. It appears that the exhaust manifolds and risers are the original and I'm wondering if I should replace them before...

Want to make sure a 36' building is deep enough for a 250 DA on a trailer with the outdrive up? Seems like it should be, but just thought I'd ask to be sure.

This may sound like a funny question, but I am getting ready to have a 24' x 36' x 12' high pole barn built with 10' high door and would like to know if a 95 to 2000 250 sundancer on a trailer will fit through the door?

Bought one of these Saterday and changed my oil. It worked great. They include an adaptor that screws onto the end of Merc dipstick tubes. 12-15 pumps and it sucked oil until it was full. Emptyed it and reconnected the hose, another 10 pumps brought maybe a half quart of oil out and the engine...

Where is a good place to look for surveyors? How is the survey handled in the buying process? Say I go look at a boat. Everything looks good and I'm interested in buying it. Is a sales agreement drawn up then pending survey? How does one allow for some flexibility in price in the sales agreement...

I think I'm going to buy this model GPS/Sonar. Has anyone used this model and what is your opinion of it?

I'm replacing the old outdated fish finder that the boat came with , with a GPS/Sonar unit. I would like to mount the new unit in a different location, but that will leave the old screw holes through the top of the dash exposed. Is there any way to close these up so they won't be visable...

Just wondering if anyone knows about what speed these would cruise at at what rpm? What is they're top speed at what rpm? Also any estimates on fuel burn at cruise? Thanks

Saterday I got out to test a Revolution 4 , 14.6x15 test prop. The boat is a 1990 220 CC with 5.7 260hp with Alpha. What a difference over the 14x17 aluminum prop! With 3 people on board and a full (58 gal) tank of gas, trim tabs full up and outdrive full down the boat comes up on plane very...

My 1990 owners manual for a 5.7 Merc says to use a straight 30 weight for below 70 degrees and a straight 40 weight for above 70 degrees. It specifically warns not to use multi weight oils. Has this changed since 1990? I see where Merc is marketing a 25-40 weight oil. Would this be OK to use or...

We were out on a lake today and pulled into a courtesy slip at the marina. While we were sitting there on the boat the guy in the next slip came walking down to his boat and asked me what size my boat was. I replied 22 foot. He said "must just be deep". I was alittle puzzled by his replie. A...

Just recieved a Mercury Revolution 4 prop for testing and it has the PVS. I know the idea behind the PVS, but just wondering if any one has any real world experience using it and what the results were for them?

Just wanting to know what I should expect as a top speed for a 1990 220 CC with a 260hp 5.7 merc with Alpha? The reason why I am asking is because I was out today with a GPS to check top speed and was surprised to find I was only running 36mph @ 4500rpm WOT. The prop is probably the original...

Are there any rules of thumb regarding estimating fuel usage? I know there are a lot of variables involved in estimating fuel usage - wave direction, wind direction, currents, ect, but wondered if I could get a ballpark estimate of what to expect in a steady cruise state. The boat is a 1990 220...

Does anyone leave a battery "on" while the boat is docked? I've been turning mine off, but I got to thinking - what if the boat developed a small leak and the power is off so no bilge pump. What is the common procedure with batteries - on or off docked?

Just wondering which way you prefer to dock and why?

Thinking about getting a SS prop for my 1990 220 CC with 5.7. The revolution 4 was listed in every catagory on Mercury's prop selection page. It also showed 14.625 x 17 as being the right prop for my boat. Just wondering if anyone is running one of these props and how do you like it?

How do I tell what drive ratio I have? 1990 5.7 Merc with Alpha.

As a replacement carb for a quadrajet which carb do you like best (or recommend) and why? Throttle response, fuel economy, tuning, durablity, ect.

Recently bought a 1990 220CC with the 5.7. Test drove the boat for about 45 minutes and ran nice. Brought the boat home and didn't have a chance to get out for a week. Took it out Saterday evening and ran for about 2 hrs, ran fine. Docked it. Went out Sunday morning to start it, started up and...
