    mercruiser 120 stalling

    1972 starcraft nova sn 3331071 Thanks for reading, and thanks for any help. My old 1972 mercruiser 120, sn# 3331071 is stalling half way through the day. The last time I took it to the lake it ran fine for half the day (with intermittent use). When I started heading back...

    mercruiser 120 missing, stalling

    My 1972 mercruiser 120 was giving me some problems a couple days ago. I had my 1972 Starcraft Nova pretty well loaded, 5 adults in the boat with one adult being pulled on a tube. At about 3,300 rpms it would quickly drop in rpms like I was pulling the trottle back. It did this twice, and then...

    trailer bearing failure

    I have a 1972 Starcraft Nova (about 18') with a mercruiser 120. I store it outside at my sister's place over the winter. I was towing it home a couple days ago and a bearing failed on me. I don't know what this says about me, but I didn't notice it until the next morning. I noticed the right...

    second stripped drain plug

    I have been using my Starcraft Nova with a mercruiser 120 a little late in the season in Michigan. To protect the block from freezing and cracking I have been draining the water each time. Somewhere along the line the block drain plug got stripped. So I bought a new one and put it in today...

    Is engine coupler toast?

    mercruiser 120 (sn 3331071) MC1 outdrive 1972 Starcraft Nova aluminum boat I replaced the transom plywood, and I am in the process of trying to get things back together. The alignment seems wrong. I thought it was aligned, but then I rotated the engine, and the alignment is off. Is the...

    1972 Starcraft Nova 18'

    Re: 1972 Starcraft Nova 18' Well I have a lot of it together. I still have a few concerns. Why does the front engine mount have to be at it's lower limit for the alignment to be good? I would have liked a little more room to work with; I wonder if I screwed something up along the way, or if...

    front mount, mercruiser 120 installation

    Re: front mount, mercruiser 120 installation follow up I went to the local Marina Store to get an opinion. We concluded the rubber bushing was beat up on the part of the front engine support that bolts to the engine. He sold me a new used one, support with bushing installed, for $105. It...

    belt change Mercruiser 120

    I know there are no dumb questions, just dumb people, right? I think I might be one of those. In changing the alternator belt on my 72 merc 120 (sn 3331071) I moved the top pulley slightly; does this matter? Was I suppose to mark it or something. Somehow I thought maybe the valves might not...

    front mount, mercruiser 120 installation

    I just replaced my transom plywood in my aluminum 1972 Starcraft Nova. I am going to install the engine tomorrow. Here is a pic of the front mount before I redid the transom. Should these fabric washers be here? The material looks similar to the rear engine mount fabric washers. As you can...

    1972 Starcraft Nova 18'

    Re: 1972 Starcraft Nova 18' Here is a little update. I have been treating and painting the transom plywood for a few days. First I did one heavy application of a mixture of linseed oil, varnish, and mineral spirits. Then a slightly thinned application of rustoleum oil based, and then two...

    1972 Starcraft Nova 18'

    Re: 1972 Starcraft Nova 18' This might be a better post for the mercruiser section, but I'm wondering if my trim pump will be toast. I let it drain out. It has been sitting in the boat like this since I took the transom apart a few months ago. The manual said you shouldn't let it drain out...

    1972 Starcraft Nova 18'

    Re: 1972 Starcraft Nova 18' I made a little progress today. I cut the final keyhole and drilled the six bolt holes. I tried a router for a little bit, but then went back to the jigsaw while cutting the keyhole. I even did a test fit to see if all the bolts would go into the holes; so far so...

    1972 Starcraft Nova 18'

    Re: 1972 Starcraft Nova 18' Thanks, GA, it helps to get some reassurance on a first time project like this. I appreciate the help. I did a transom on a 15' aluminum boat (outboard of course) and it sure didn't take much to get a hole misaligned. I think I drilled a few holes for the through...

    1972 Starcraft Nova 18'

    Re: 1972 Starcraft Nova 18' I got the transom plywood cut. I had one problem to figure out. The two 3/4" pieces seemed to be bowed ever so slightly, unless it was partially an illusion because of the transom aluminum skin sagging. I tried the two boards sandwiched together both ways, and...

    1972 Starcraft Nova 18'

    Re: 1972 Starcraft Nova 18' GA_boater, Thanks for the advice. I appreciate any help I can get. Here's the pics of what I bought yesterday. I even got a little measuring calibers; I have to try to be accurate. Looking at the old transom, I wonder what the quality was of that plywood; it had...

    1972 Starcraft Nova 18'

    Re: 1972 Starcraft Nova 18' This was probably the wrong way to do it, but I took the outside section off in one piece. Time will tell it this method will make the repair harder.

    1972 Starcraft Nova 18'

    Re: 1972 Starcraft Nova 18' I think I got the transom pretty well disassembled now. I tried to take a lot of pics in an effort to help with putting it back together. That wood was very rotted.

    1972 Starcraft Nova 18'

    Re: 1972 Starcraft Nova 18' Thanks to my kids swing set and some items from Harbor Freight, I got the engine up and moved forward in the boat. There was one item I did not have to remove that the manual said to, the shift cable. It might be hard to tell from the pic but it kind of made a big...

    1972 Starcraft Nova 18'

    Re: 1972 Starcraft Nova 18' I'm making a little progress. I removed the seats to make more room to work. I am planning on just moving the engine towards the front of the boat instead of removing it. In the second picture you see an ugly looking pipe that comes out of the transom and then...

    1972 Starcraft Nova 18'

    Re: 1972 Starcraft Nova 18' I wasn't sure if those pics would post, but looks like it worked. See how close the top of the bolt is to the pulley, doesn't seem right. The other pic shows my redneck attempt to stiffin up the transom.
