I don't know where to start! 1989 Sea ray 160 restoration

So I picked this beauty up a few months ago. It was just too good of a deal to pass up. The trailer made it home so its already worth more then I paid for it, :D so I was happy with my purchase. However im feeling overwhelmed with where to start. What I have here is a 1989 Sea Ray 160 Bow rider with a 100hp Mercury outboard. I have to imagine the boat sat outside for at least 5 years with out a cover on it. Or at least it didn't have a cover on it the last few years.

the outboard appears to be in good shape and I've had it running a few times for short periods of time off of a small tank. However it doesn't stay running that well. The tank I'm using is a small plastic one with a fuel hose running to it. I also think the primer bulb on my fuel line has a leak in it which introduces air while it running and doesn't help the situation. I did try removed the lower unit to inspect water pump impeller as I couldn't see any water coming out of the drain hole while it was "running". Long story short its not coming off very easy. I fear that the vertical drive shaft is slightly fused or corroded onto the upper drive shaft? Im not sure if those are the correct terms but basically when the fasteners are removed from the lower unit it does not simply slide off. It acts as if its still fastened. Im working it off with some plastic and wood wedges for now.


On to the boat/hull..... The hull itself looks to be in great shape despite needing a good wash and maybe have the oxidation cut down. I dont see any repairs or damages or any stress cracks etc. The transom appears to be solid as well. Just from knocking on it though. I haven't tried taking any core samples yet.

The floor/deck of the boat is complete trash. It needs to ripped out. I'm not sure about the stingers but I can only imagine. It looks like I have most of the interior except for the rear bench seat? It looks like it was a bench anyway. The vinyl is all there too but its dry and dirty. As for the floor that where I planned to start im just not sure exactly how to go about it. As you can see in one picture it shows where the fuel tank is towards the stern from the ski locker. The wood was all rotted and ripped up there. You can see how rotten it is around the perimeter.

My question really is where do I start? I can demo the interior no problem but I dont want to get ahead of my self. Ill take lots of pictures but what measurements do I need? How should I go about ripping things out? Anything I should try to save?

I really appreciate any advice. Im sure once i get started Ill feel more comfortable bu ive been hesitant to do much. I am very good with electronics and quite handy with mechanics as well. Ive been a car/engine junkie my entire life and in the last few years gotten into boats. This is however my first outboard. In the last year I completed a total gut and remodel of my kitchen including removing a wall, plumbing, gas work, electrical and structural changes. Everything was a first time for me except the electrical and some plumbing work. I like to learn new things but I like to do them correctly or at least try. So this is why Im asking for some advice on where and how to start with this.

Thanks for any information! Boating season is coming up on us quickly!

Nice looking boat Eathan. Don't worry about the tear out part, that's easy.

About the measurements: what I did was anything I wasn't completely sure about I measured, wrote down, and took pictures of the tape measure measuring the measurement, but I tend to over-do things. I wasn't sure either, and since there isn't another boat like mine in this part of the country; I thought I needed to.

I found most of my damage by tap testing around my transom after I pulled the floor. I knew the floor was shot and when I got all of the saturated foam out, it was way easy deciding what to demo next. I didn't need to core drill stringers to see if they were damp since you could see the water in the cells of the wood. Mine weren't wrapped in glass so they rotted out completely.

I work on aircraft structures and know a lot about composites:plane:, but knew nothing about boats :fish2: until I found iboats. Not that much different and I have learned so much about the little differences between them.

If it were me, I'd jump right in and get started and there are all kinds of help here if you get stuck. I have meet some really good friends here and I know they are here if I need them. Summer is just around the corner, hopefully.:pray:

Re: I don't know where to start! 1989 Sea ray 160 restoration

Well........wow. I would start by first asking myself if I really love the boat. I will not lie to you and a restoration will consume money and occupy space so you need to be in love with it. I see another boat in the background so I take it that this is not the primary toy.

First the motor. That is called a clamshell Merc by the way the cover opens and closes. I am willing to bet that a good day or so of maintenance will restore life back to it providing the compression is good. Carbs, plugs, check the wires for being brittle, impeller and a good de-carb when it is running. If you know the boat needs work then the motor needs to be removed and placed on a stand.

Next strip out the carpet and start some "surgical" examination of the deck, stringers and transom.

Remember, you need to love the project more then your bank account. That is about a $2500-$3000 boat in good condition and if you put $2500 into it you will still have a $2500-$3000 boat.

Now with the gloom out of the way.......... iboats is going to be making some changes to it's Restoration Supplies in it's store and they are very close to being released (call that some insider trading knowledge ;)) so supplies will not be a problem.

If you have the time to devote...... love the boat......the motor checks out....... go for it.

I will gladly trade you......I will take your "tight for space" garage for my situation.....no garage :(

If you do love this boat and your decision is to keep it and repair it, then I know for a fact what you'll be doing in your spare time... I see a lot of repair work ahead of you. But if you seriously like that type work, have at it. You will become vary familiar with sanding and grinding and the use of many power hand tools as well. But IF you do finish the project, your self satisfaction will be your total reward...

Good luck, everything you will ever need to know can be found right here...FYI, I don't intend to insult you in any way, but I offer this observation: I have a 1989 Mercury 150, I have removed my lower unit and replaced the pump etc. There is a "hidden" bolt located under what is called the trim tab. My lower unit has 4 studs (2 on each side) and with one stud at the front opposite the prop. The trim tab on my motor has to be removed to access that hidden bolt located at the rear of the lower unit. Once all the bolts/nuts were removed from my motor...it was just a matter of a little prying to get it seperated. Keep in mind, that this info is for my 150, don't know for certain if your 100HP is the same. Dan

Re: I don't know where to start! 1989 Sea ray 160 restoration

sounds like one of the first steps will be to remove the motor -- but suggest a cherry picker for that job, whenever you get to it. Can move it around in the garage that way.

Re: I don't know where to start! 1989 Sea ray 160 restoration

Sorry about the super delayed response I was away this weekend and didnt get a chance to check on here.

Thanks for all of the reply's!

The other boat in the picture is indeed a "primary" boat for me. This sea ray is more of a project for me but in all honesty im not "in love" with this boat. It was just really really cheap for what I got and I figured I could do a basic restore on it and have another boat to bring more friends out in. The other boat is a 85 Wellcraft Scarab 1 21' and it seats 4 well and you can squeeze 6 people if you have to but everyone is sitting down and no one can really move about the boat. I can see myself buying a larger boat down the road to facilitate more people.

So after reading every ones reply's im thinking i may just try to sell it as a project. I don't know yet. I always have quite a few different projects going on at the same time but I do enjoy learning new crafts. Ill have to put some thought into what I would like to do with this i suppose.

Daniel1947 - No insult taken! I appreciate you mentioning your experience. I too have 4 studs (2 on each side) and there is one nut that is located just forward (towards the bow of the boat) of the zinc tab. This bolt is basically located on the bottom of the cavitation plate right above the prop.

So i do have 5 nuts removed currently. If im understanding what your saying about the hidden fastener underneath near the trim tab? So this is on the lower unit opposite end of the prop? Like the picture below with the red arrow?

Or are you talking about the bolt that is under neath the zinc tab? I have removed the zinc as well even though the hardware holding it on doesn't seem to fasten the lower unit to the mid housing or whatever its called.

As for the first step I agree removing the motor is a good idea. I have a few chainfalls hanging in the garage that should make this job fairly easy.

Thanks for the help!

If this doesn't work I will try and PM you.

lower unit.jpg

pic is small...sorry

You should have 2 studs number 5, 2 studs number 6, 1 stud number 4 at the front.. Trim tab #27 is held in place by bolt #28; when you remove the trip tab #27, there is a bold #31 hidden and is removed from the bottom. At least this is the way my 150HP unit comes apart. Let me know if you need a larger pic.

Re: I don't know where to start! 1989 Sea ray 160 restoration

I apologize again....not real used to placing pics. the numbers referanced above #27, #28 and #27 are wrong. They should be Trim tab#77, and the bolts should be #78 and #87. I will get the hang of this one day.
