    Reworking prop / Changing pitch???

    I am looking at a new/used prop to replace my 19 pitch one. I am looking to go to a 17pitch. Is is possible to have a reworked prop that started out as a 19, then was redone to a 17? The one I'm looking at shows "48-74886-19" on the hub, but on the side, between the blades, shows "48-74886-19...

    Yellowish snotty, slimy, stuff...

    I have taken my boat out on the lake a few times since we put the new motor in and it is running great. The only thing I've noticed is when I pull the plug after each use, there is a yellowish, snot looking substance coming out from the bilge. The engine is not leaking and there is no water in...

    Alpha prop replacement... size questions?

    I am looking to get a little more "out of the hole" performance out of my 3.0 Merc. My current prop is a 19 pitch, unsure of size; probably a 14.5? My question is this, what size prop would be ideal for my boat? Its a 16.2" Deep V Hull style boat with a 3.0 Merc. Should I go down to like a...

    Special thanks...

    Thanks, again, goes to wncrjb for helping me get the boat even closer to the water! First, he drove to Knoxville (2 hours) and helped me get it assembled and timed, then he rebuilt my carb and checked a bunch of other odds and ends for me! The boat runs great now and I can't say thanks enough...

    She's ALIVE!

    Well, after sitting since late July, the boat is alive again!!! VERY special thanks to wncrjb, who spent the weekend in Knoxville just to help me get everything together and tuned. YOU ROCK MAN! The newer engine is a combination of an '84 block, a '72 head (as best we can tell) and about a...

    Do I now have a 130 or 140?

    I tried to find the previous posts about the difference between the 130 and 140 Merc 3.0s but came up short. What makes a 130 a 130 and a 140 a 140?

    About to give up...

    After being outside in 90* weather all day trying to assemble the engine, install it and align it, I'm now trying to get the outdrive back on. I've followed the manual but can't get the outdrive to go any further in than just past the UJoints. Yes, the input shaft is going in/thru the...

    Need help with 3.0 rear motor mounts... QUICK

    I'm running outta daylight and I've gotta get this motor at least dropped in so I can align it before I've got to return the alignment tool tomorrow. I dropped the motor in and it looks like the motor is sitting about an inch too high (looking through the gimbal bearing). There were 2 1"...

    Fuel pump gaskets?

    I bought this kit for my engine install: I am trying to swap the fuel pump from the old motor to the new... It appears there were two gaskets with the pump assembly, almost like an upper and a lower that are stacked. Which gasket did I get with the kit? Can anyone help me figure this out...

    3.0 swap... first prob?

    While swapping parts over from the old block to the new block, I noticed the way the flywheel bolts on to the new block is diff from the old one. The old one had bolts that screwed into the end of the crank... the new one seems to have studs in the crank and nuts that hold the flywheel on...

    Aligning a 3.0... gotta get it right tonight...

    In a twist of my luck, my local SeaRay dealership is going to loan me their alignment tool tonight. Since I've gotta get it back to them by 8am, I've only got one night to mess with aligning this new engine. Can anyone run the process by me? AFAIK, it seems like you put the motor on the...

    Setting timing/distributor

    I will be assembling my 3.0 within this next week, with the hopes of getting it started and in the water by Sunday... The only part that I don't quite get (yet, REALLY should) is setting timing. All of my vehicles are and my previous ones have been distributorless, so I've never learned how to...

    Freshening up motor for install next weekend!!!

    Well, things are finally falling into place. I picked up the shortblock on Sat and the rebuilt head and outdrive gaskets and engine gasket kit should be here sometime this week. I broke the short block down to check it out since it was a pull out. The cylinder walls and pistons look fine, the...

    Removable freeze plug?

    I just bought a short block for my boat to replace my dead 3.0. Anyway, the most front freeze plug is actually removable, with a bolt from the looks of it. I've seen these a few times. What is the difference between these and the standard brass-looking ones?

    Part number for ujoint bellows?

    I'm thinking while I have my outdrive off, I'll see about changing my ujoint bellows and possibly my exhaust bellows. I have an '87 3.0 Merc w/ Alpha One. Anyone have any usable part numbers for said setup? Are they expensive? My ujoints and gimbal look really good, but I'd rather change...

    Picking up short block on Sat... anyone close have an alignment tool?

    My wife has been rather upset w/ me about the boat lately because I've been obsessed with fixing it and actually using it before the season is gone... Anyway, I am picking up a shortblock on Saturday. Does anyone here live close to Knoxville, TN and have an alignment tool I could borrow? Or...

    Painting my outdrive?

    I have an '87 Alpha One unit that I currently have off the boat. I'd like to paint it, as it currently looks to be badly oxidized. Is there an inexpensive, yet durable way to do this?

    What else to do when motor is out?

    Since my motor is out and HOPEFULLY I'll be swapping in a new one next weekend, what else (if anything) should I change while the motor and outdrive are out? I'm already going to have a oil drain installed. Do I need to replace the gimbal bearing, u-joints, or anything else? What would be the...
