25 Seafari
well I ve started working on the 25 Seafari I picked up a few weeks back, since Ive had her Ive been so busy I havet had a whole lot of time to get started on the repairs, the first things ive done were to go through the boat and both engines to see what was needed, the starboard engine needs a trip pump replaced so I removed the old pump while the motor was still hanging on the boat,, no easy task Im telling You. the top bolt on the engine mount had a locking nut thingy on it and I had to cut the head off the bolt to get the bracket loose and all thge bolts were salt seized, I got the torch and hammer out and I got it off! Ive found a replacement pump and will be picking it up tomorrow and purring it back on this weekend, I have both engines turning over and they both have fire, and good compresion, Im going to clean the carbs and replace the fuel lines before I try to run them,. but they look to be in very good shape, I also want to pull the fuel tank and clean it out and replace the fill and vent hoses. I went through the electrical system on the boat and other than a few switches that are bad every thing works except the bilge pump and mast light!, heres a few photos of the trim pump removed

Phil,
Be sure to check the steering arms on those Mercs. They are known for rust through problems if they've been in the salt. The carbs are a piece of cake to clean if you have the Merc factory service manual. If you don't already have one, you can find them used on ebay for around $25. Don't bother with the after market manuals. Dave

spent a few days working on the 25 over the weekend,
first off on friday i worked on the port engine a little , I cleaned the carbs and hooked up a 6 gal. fuel tank to it and it fired right up!! couldnt believe how good it ran!! I hope the starboard side cranks and runs as good, Ive found blown engine on CL Im going to get this week so I can get the trim system off it and put on the starboard eng, then Ill see if she will run. I then dove into the fuel system, I removed all the old fuel hoses and got the rear 50gal tank loose and ready to come out, its gor about 15 gals of old stinking gas in it so ill have to pump it out before I can lift it out, Then on to the original dual tanks in the floor, after bout 2 hours of digging out foam and cutting old hoses, the old tanks were oin the ground. The rear bulk head wall behind the tanks is rotton and will have to be replaced but the floor and all the stringers are solid as a rock! Im going to clean out the single 50 gal tank and mount it under the floor where the old tanks were and run all new hoses. i also checked out the hydralic steering and found a leak in a hose going from the transom fitting to the engine , Going to order new ones in the morn.

Those pics bring back some memories. You've probably got a bunch of wet foam under the tank deck in the original tank compartment.

Just incase you didn't see this, I'll share it with you and the others as well. It makes some good points about tank installation. http://www.yachtsurvey.com/fueltank.htm Good Luck and I look forward to following along. - lance aka: BigLew
