Can anyone direct me to a site or have any instructions on removing an inboard? I understand and can do the obvious, I'm just worried about the seacocks and suck that could sink the boat!

We have an inboard and just looking at it I'd say "find a yard". That thing has two holes below the waterline (intake and shaft) and the exhaust just above. Plus as far as I can tell it's gotta come out the companionway.

Are you removing permanently or temporarily?

temporarily, I do have someone in my marina that has already taken his out, in the marina, problem with " finding a yard " around here is that it costs about $500 to pull it out and relaunch and 10 a day to store untill the guy fixes it.

You should be able to close the seacock and as long as it does not get knocked off the boat removing the engine, it should be OK. You can leave the shaft in place to keep the gland plugged up also.

I guess you can remove the engine very carefully

with the boat in the water. My experience with the local yards is it costs a boom and a mast to haul and store but rates are more reasonable if they can come work on your boat (~$90/hr)

Yeagh, I bought " Even Keel " about a two months ago, inboard supposed to be fixed, not fixed, mechanics have to remove inboard to open her up to see what is wrong ( can't do it inside the boat). The good news is I have a friend of a friend who is only going to charge me $50 per hour! But, I have to pull the engine and bring it to him. I was told to have some kind of plugs handy just in case the seacocks don't work, thank you for your input!

Pura Vida!

On pulling an inboard -- I've found it helps to disassemble the engine as much as possible before attempting to remove it. At the least, remove exterior accessories such as transmission, alternator, starter, (raw water pump & heat exchanger if so equipped), etc. I've also removed intake & exhaust manifolds and even cylinder heads before pulling the short block. When it comes time to reinstall the inboard, consider reversing those steps. Some techs prefer to install the cylinder head while still outside the boat, so as to get the engine closed up before exposing it to bilge crud. I'd make that choice on a case by case basis.

You know your friend of a friend, but if you get a good professsional who will charge you $ 90.00 per hour there will be no question later about whose responsibility what was. A stranger can look at the engine in the boat and tell you what you can do to make his life easier and keep his hours down. Then you know that when you put it back together it will work because he either did it or told you what to do. I once went out on a boat that a friend of a friend had fixed only to have it smoke and conk out in the middle of the LI sound. That wound up not being such a fun afternoon. On the other hand, I bought my boat in December and had a pro come out and work on it. The motor was working properly but he did some upgrades/repairs (installed raw water see thru filter/install new stop cable/repacked stuffing box). He had to pull the engine to redo the packing because the shaft is too short. Best $90.- an hour I ever spent. The boat ran 14 hours straight at 2700 - 3000 rpm fighting a wicked current on the Hudson without a problem.
Good luck.

I should have made myself more clear, the friend of a friend, is a service tech for cummings diesel, plus works on marine ( 15 years ), but good advice! Around here in Charlotte, NC, finding a "professional" is nearly impossible. Thanks everyone for your input!

I pulled a Yanmar 7 HP diesel inboard out of a friends boat without too much problem. We disconnected everything. He did one side, I the other. Disconnected the shaft but just left it in the boat. Removed alternator and pump, disconnected all wires and cables. Removed motor mounts. Left tranny on. It only weighed about 175 lbs full.

I brought some 2 x 4 s cut to various lengths. We used these to make levers and wedges and lifted and slide the motor into the quarter berth. Then we dragged it into the salon. I made a block and tackle to lift the motor using the boom. Then 3 guys slung the boom over the dock and lowered the motor into a dock cart. 3 guys pushed it up the dock and we lifted it into my mini van.

Once rebuilt (cost about $4K) we just reversed the process. We had a couple of bottle jacks to use as well but my 2x4s worked fine.

I only had to put together the side of the motor I took apart, that made it alot easier.

Yeagh this is a 8hp Yanmar, do you know why the engine had to be rebuilt? I am looking at doing the same thing, and if you know, was it hard to find parts? Seems to be a pretty big obstacle on a (1980 ) motor.

The water pump slipped off the belt, the motor overheated. The head cracked very slightly so there was no compression.

Parts can be found. There are a few items that are impossible to get, like the crank. Good thing the block and crank are bullet proof. My friend got a new head, the motor runs like new.

To be honest, everytime I get offshore in big rough seas with no wind I wish I had the inboard.

By the way, we got the motor out in about 4 hours x 2 people with his wife handing us tools, etc. 3 guys did the lifting. It took about 4 or 5 hours to get it back in and running. While the motor was being rebuilt he pulled the fuel tank and had it cleaned.

I asked for nothing, but my friend gave be a $100 West Marine gift card which I used to buy foulies. Thanks very much!

Talk about cheap labor! My diagnosis is still dependent upon surgery, we have to open her up! I hope is not going to be too crazy! I do have the crank though!
