    Inboard boat maximum horsepower ratings?

    So...if you subscribe to iboats university you'd know it's highly "illegal" and "unsafe" to operate a boat equipped with an outboard motor even 1 horsepower over the boat's horsepower capacity. There is no wiggle room. You will go directly to jail, and probably end up on the "no fly" list...

    350 Chevy dripping exhaust?

    I have a 1973 Chevy truck with a carb'ed 350. Today I drove about 5 miles and stopped for gas, and noticed my tailpipe was dripping quite a bit of water. I know this is normal on a cold morning but it seems weird after 5 miles on the highway on a warm day. (about 65 outside) Engine should have...

    Zinc chromate primer drying time?

    I've got a whole bunch of Mercury outboard parts that I need to paint. I got some zinc chromate primer from Moeller, and the can says "recoat within 1 hour or after 48 hours". Is that just additional coats of primer or does that include the paint? Do I have to wait 48 hours before the final...

    Inline 6 cracked water jacket?!

    I have a '73 1500 that I'm working on. This motor sat outside in the weather uncovered for a few years so I'm replacing just about everything. The powerhead was rebuilt just before it sat and only has a couple hours on it. Today I pulled the cowl support off and found this on the water jacket...

    What to do with an old boat hull?

    I'm thinking about picking up an old boat for cheap because I want the outboard. The hull is garbage but I have to take it. What the heck do I do with a 16' fiberglass boat hull? How much does it cost to get rid of something like that? I don't think they take things that big at the local garbage...

    Fixing up metal outboard gas tank?

    I have this old 6 gallon OMC metal outboard tank that I'd like to clean up and paint. It has some nasty stuff inside so I started to take the fuel gauge off so I could dump it out. One of the four flathead screws is rusted on...any suggestions on removing it? Normally I would take a torch to it...

    Removing crank bearings from inline 6?

    I have a 1973 Mercury 1500 that seized up and I'm trying to salvage what I can. I pulled the crank but I can't figure out how to remove the main bearings and the end cap under the flywheel. What am I missing? I want to see if the journals are usable...

    Temperature gauge for Mercury inline 6?

    I'm putting together a "1973" Mercury 1500 with a new powerhead and a bunch of new parts. I'd like to have a temperature gauge to help protect my investment. (along with a new tach, water pressure gauge, and hour meter) Where would I install a sending unit for the temp gauge? Is this even possible?

    Need help picking a prop for speed

    I have a 1973 Glastron/Carlson CV-16 (16 foot) with a Mercury 1500. I've currently got a 19p aluminum 3 blade prop and the last time I had it out I could hit 50MPH on the GPS at around 6300 RPMs. I know the motor is spinning too fast, and since then I have removed a ton of soggy foam and plywood...

    Which lower unit should I use? Fix bent skeg?

    I'm putting together a 1973 Mercury 1500 for my boat. Right now it has a late 80s lower unit with a bent skeg. (from a Mariner) I have also come into possession of another LU, mid to late 70s. (I can post the serial number if it makes a difference) This LU has a straight skeg, but somebody has...

    Handheld radios?

    Me and my friend are fixing up our boats for a camping trip this summer, and I'm sure you know how reliable old boats are. :lol: Since our cell phones don't work at the lake, I want to get some handheld radios so we can talk to each other. I guess there are a lot to chose from...what kind of...

    Can I convert my 1973 Mercury 1500 to distributorless?

    I'm trying to fix up my 1973 Mercury 1500 - I have a new rebuilt powerhead, but most of the electrical stuff on the motor is either bad or suspect...as is my power trim. I found somebody selling a complete 1979 115hp motor that has a bad powerhead but new electrical stuff, and it's super cheap...

    Painting my Mercury outboard?

    I'm fixing up my old 1973 Mercury 1500, and I'm excited to find some reproduction decals for the cowling on ebay. I will also need to repaint the entire outboard, and I see that Mercury sells "phantom black" in 12oz spray cans. Is it going to come out good if I just use rattle cans to paint it...

    Can I rebuild my starter?

    I'm working on a 1973 Mercury 1500 that has been out in the weather uncovered for a few years. I got a battery hooked up so I could try out the starter, and it turns over really slow. The engine spins free, so there is something wrong with my starter. Is it possible for me to rebuild this...

    Rotten distributor wires on Mercury inline 6...what to do?

    I'm trying to fix up my 1974 Mercury 1500 which has been sitting out in the weather uncovered for a few years. I haven't attempted to start it yet, but I'm really worried about the old rotten wires coming out of the distributor trigger and the stator. I plan on rewiring the whole motor, but...

    Taking boat off the trailer?

    My poor old 16' 1973 Glastron has been sitting out in the weather for almost 10 years now. I finally dragged it into my shop so I can work on it, hopefully I can get it out on the water this year. I want to take the boat off the trailer so I can paint it and replace the bunks...but the question...

    1974 Inline six - starter won't engage flywheel?

    I'm working on a '74 Mercury 1500 that has been left out in the weather uncovered. My starter was frozen, but I was able to free it up and it spins great without load. The problem is now that I bolted it back onto the block the bendix doesn't engage the flywheel? The starter motor just spins at...

    '74 Merc Inline six - dead starter?

    I'm working on a 1974 Mercury 1500 that spent the winter outside without any cover. The first thing I'd like to do is simply run the starter with the spark plugs out after squirting some oil in the cylinders to free everything up. Today I tried just that, all I got were sparks. I hooked a set...

    Mercury inline six wiring diagram?

    I have a 1974 150 inline six mercury outboard and I need to "hot wire" it to get it started due to bad wiring in the boat. I need to know more about the wires coming out of the switchbox. From top to bottom, the first one goes to the coil, and the third one is positive, what are the other two? I...
