what to replace while motor is out?
 

I am kind of new to boating.I got out of motorcycle track days and went into boats.I traded my trackbike for a 1985 scarab 1 that needs more work then I wanted but I really love the boat! I have the motor out to repair motor mount stringers and I was wondering what to replace while its out? I know the gimble bearing,ujoint bellows ,trim sensers but I was wondering if there is a must do that I'm missing . thanks in advance,
Erik

If you have already taken your motor out you are more mechanical than 70% of us here.

A little more info on your setup will get you some more interest.

Welcome to boating and welcome to OSO.

Replace anything you can afford that is hard to get to like bilge pump and hoses. Blower motor and hoses. Battery cables that are secured to the stringers or transom. stuf like that.

I asked a similar question some time ago. I had a water leak which was the freeze plug. So while one of the motors was out I replaced the bilge pumps. But beings you mentioned your boat was a 85 Scarab, I had a 86 Wellcraft and after removing and reinstalling the motor one weekend the Engine Coupler went bad. If I only knew it was going to go bad I would have replaced that part. I can only assume that yours is set up that same way.

Transom gasket and upper and lower swivel pins.

Everything mentioned above, plus the starter.
Basically anything that you know will be a bltch to reach when the motor is in; and is less than a couple $100 bucks.

Verify the extent of the damage to the stringers before you worry about anything else. Usually threads that mention stringer repair quickly turn into transom repair, bulkhead repair, gas tank and forward stringer repair, etc.

Thanks for all the responses !it is a 350 mercruiser,the motor has a ton of room to work around it but yes I am gonna replace what I can.
I have the tops of the motor stringers cut open neatly and cleaned out and scrubbed everything really good.I am going with the seacast pour as it looks to be my best method.I drilled holes in transom and it is wet ,I know will probably lead to rot but I reeeally do not want to get into that this season! I talked to rot Dr. He said to look really good for stress cracks or damage and I couldn't find anything. If I did get into it what is the easiest way ? I am a A-tech bodyman by trade ,I am pretty capable of doing anything its just that I can only get the boat in the shop on weekends and don't really want to abuse my shop use ! How hard is it to separate hull and deck ,I think I'm using correct terminology ? I would like to use the pour method on that also .I knew I was gonna open up a can of worms with the thread but it gives us all something to talk about until spring time! Besides I do really need some guidance.

May I suggest that you purchase and install a - thru the drain plug- oil drain hose. IMO this is the next best thing since sliced bread -- Makes oil changing a snap!!

Welcome to OSO

Great group of people - where everyone is good looking, have above average boats, nerves of steel heading thru true 8' waves and a plethora of smart alike comments that are worth their weight in gold!

Take care and above all safe boating!!

All the above are great recommendations. Its always that one part you didn't replace that takes a dump on a Sunday, do as much as you can.

If you have rot in the transom, just do the whole job at once.

I used Seacast in a minor floor repair in a 1970s boat; and am quite impressed with the product; albeit I have not run the boat yet.

change the water supply hose

Take lots of pictures. .. we are simple people and like pictures. .. lol

Paint bildge with gel coat:boat:

Fix the transom now. I dont know where your located but where im at there are plenty of weekends left until boating season.

Along with all of the other suggestions...consider replacing the bilge blower and hoses. It's also a great time to add access lighting to the bilge so you can see what you re doing at night!!

It may be extreme but a co worker of mine actually installed a remote video camera in his bilge and connected it to his navigation network...very cool.

Have you sprayed gelcoat? That was my plan. I have about 25 years in auto body business, I have used gelcoat but never sprayed it. I have brushed it in to make moulds before. We have a spray gun for spray polyester which requires a 2.5 tip ,I think it will do gelcoat also.will it flow out smooth?

I have gotten some good ideas so far ! Keepem coming.I will try to get pics up soon!

Check the water hose transom fitting, sometimes they get clogged. For that matter, check all the cooling stuff. It's much easier on a stand.

Does this boat still have the factory liner in the bilge? if so your rot may have spread farther than you can see, I just went through the same issue and same boat 3 weeks ago they had installed 6x6s under the liner to support the motor and they didn't have any fiberglass covering them and the floor drains in the cockpit ran down the stringers right to them and they turned to mulch IMO id try to check those while you have your motor out... there are what look like drain holes just below the motor mounts look in those you should be able to see the supports and if they are wet or not...I found mine trying to figure out the drainage system on the boat and what I learned was there was only one and its in the far back just below the transom assembly and this is where mine rotted my transom...If you decide to run what you have I would suggest making some support for the motor I made stainless angle to cover all of the motor mount area to spread the weight out until I found the bad stuff....I decided to cut the liner out and go with a conventional stringer set up and leave the liner out... I'm starting my glassing job soon and I've gutted this same boat and am in the process of building it up now if you have any questions about it just ask these guys on here there is a ton of info and knowledge.. Good luck with the resto

The motor mount stringers prompt me to pull motor. They run from transom to the front of engine bay.http://s1237.photobucket.com/user/ea...tml?sort=3&o=4

I will post more pics later

Yeah that's where mine rotted also but it transferred to other stringers and the transom....that's why I ripped it all out and started fresh

Do you have any pics ?

Yeah I tried to upload one earlier but I think I have to renew my membership shoot me an email and ill send them to you [email protected]

After market or OEM ?anything to stay away from on parts I do replace?
