Has anyone tried removing old fuel from a boat? I have a 1977 Searay 240 srv 24ft Sundancer with twin 470 mercruisers. I have been working on it for a year or so and it has about 40 gals of fuel in it that is a year or so old and I feel it is most likely gone bad by now.

Well today I discovered that some lowlife pig thought it would be a fun thing to do and knife two of my boat trailer tires. If they were angry because my boat has been parked in front of my house for a while while I work on it well they are really going to be upset when I jack it up and put...

I just have a question relating to the outdrive steering pins on a mercruiser pre alpha mr outdrive. Are the parts for the mr different than the standard Alpha 1 outdrive? I need to replace the steering pin on my 77 Searay 240 sundancer. It has twin 470's and outdrives. Right now I'm fighting a...

Had an issue with the port tilt motor today on my 77 Sundancer 240 with twin 470's. Was testing the port tilt and it would go up but not down. I checked the oil and it was really low so refilled. Tried to go down again and the clear hose came off the pump and puked out the oil but didnt notice...

I have a 77 Sundancer 240 with twin 470's and MR pre alpha outdrives. I had a clear plastic hose come off the tilt and trim pump and pumped out the oil before I figured out the problem and now the outdrive is all the way up and the three button switch stopped working. I plan on checking the...

I have a 1977 240 Sundancer with twin 487 Mercruisers and need to install remote fuel filter. What I need to know is has anyone done this before and did you need to install a unit for each engine? I believe one unit will supply enough fuel for both engines but would like to have some feedback...

I just replaced a exhaust riser on the stbd engine and when I looked down in the pipe I didn't see any flaps does the mercruiser 1977 470 have them? I see a bar going across but no flap.

Well my hole in the water just smoked the stator on the stbd side and I believe the port side isn't charging either so I'm going to replace them both with an alternator conversion kit. My boat is a vintage 77 searay sda srv 240 Sundancer with twin 470's. I have put alot time,money and effort...

Has anyone out there have a done a alternator conversion on a 1977 Searay SDA SRV 240 Sundancer? I was wondering which installation the upper or lower install is easier. I am concerned about clearance of the deck or down below near the plywood shield on the strbd side and how it may all fit. I...

I have a 1977 sda 240 Sundancer srv Searay with twin 470's and I have just been working on a overheating issue on the stbd engine so I cleaned the riser and cleared all the passages. I then reinstalled everything topped off the coolant. I also installed two new batteries and hooked everything...

I have twin 470s and they show that they are running hot on the gauge but measured with a lazer shows running at 160 or less at the reservior and all points on the engine. Have changed out the thermostat and the temp sender and now it reads even higher on the gauge on the port engine, have yet...

I have a 1977 240 SDA I believe is a sundancer and it is missing the blower trim that mounts on the center top of the transom. I'm not sure whether it is made of teak or metal. It is the only piece that I am missing to return it to original shape. If you have this part or a picture of it so...

Just finially got the boat in the water after working on her for the last 9 months and the starboard engine is over heating and the port running a little warm. I have replaced both water pumps on the outdrives and they were pumping fine on the muffs and ran only a little warm on the starboard...

I have twin 470's with I think they are rectifier charging sysyems. The port side charges at 13.5 volts where the starboard side charges at 16.5 to 17.0 volts. It seems to me that is a bit on the high side and can damage my batteries. Does anyone know if there is an adjustment that can be made...

I'm going to put new seals in the lower outdrive carrier and I bought a standard and a line cutting seal but was wondering which seal goes where. I would presume that the line cutting seal goes to the outside but would like to know for sure anyone know?.

I am curious where water can enter the outdrive oil when all I have done is run it with muffs, it hasn't been in the water yet. I have earlier replaced the carrier seals, Shift shaft seal,and the waterpump complete from bottom to top. The lower was pressure tested and passed with no pressure...

I am just getting ready to install the new bellows on the second outdrive I have had to fix because of a previous bad installation and I was wondering if anyone out there have an easy way to apply the adhesive to the flange and bellows where it doesn't dry up before the bellows are installed. It...
