    Mercury 7.5 HP Motor Refresh (1969 model year)

    Another Update . . . I ran the engine some more today. I noticed that it was misfiring a bit, so I pulled the spark plugs to check them. It turned out that the gap on one of them had closed up pretty much . . . probably when the plugs were out during the rebuild, etc. Anyway, I reset the gap...

    Mercury 7.5 HP Motor Refresh (1969 model year)

    UPDATE: I hooked up the fuel tank and ran the engine for the first time after the rebuild. It sure has a lot of compression versus what it used to have :eek: I added some extra oil to the fuel for 'break-in' purposes. . . probably about 30:1 instead of the regular 50:1 I varied the speed of...

    Formula 330SS Bulkhead Replacement

    Getting back to my 'update' post from August, I plan on adding additional bonding of the stringer grid to the cockpit sole and hull during the Spring prep work this year (2017) So, using my 3D diagram, here is the plan. The Red is the existing bonding that I added back in 2014 when I replaced...

    Formula 330SS Bulkhead Replacement

    Another follow-up on this project . . . I came across a 3D modeling software that would have been quite helpful when I started the rebuild. I have taken some time based on the knowledge that I gained in repairing the structure of the F-330 SS to 'build' a 3D model of it. Here are a few...

    Bought a 1998 Sea Ray Sundancer 270 wide beam with rot...

    You are welcome . . . sorry that I can't come see the boat today, but the drawings that Sea Ray sent, plus the pictures you posted are the next best thing to being there. I *think* this would be the way to approach the repair . . . Here is your boat's structure . . . I would . . .remove...

    Bought a 1998 Sea Ray Sundancer 270 wide beam with rot...

    As far as the fuel tank placement in a boat's structure . . . You want the fuel tank surrounded by the strongest portions of the structure and that is most often between the main stringers. Sometimes the fuel tanks are surrounded by air gaps, which are supposed to provide room for evaporation...

    Bought a 1998 Sea Ray Sundancer 270 wide beam with rot...

    Looks like Sea Ray sent you some pretty good information with those shop drawings, etc. It is a lot more than most of the folks doing restoration work get. So, you should be in good shape. Based on the pictures that you posted, etc. I have made a 3D image of what I think the bulkhead and...

    Bought a 1998 Sea Ray Sundancer 270 wide beam with rot...

    Cruisers still need the support of stringers and bulkheads, but the accommodation of living space below deck means that the designs are a bit different. . . . Usually there are as many if not more stringers since often they cannot be as tall as those of smaller boats. The height of the boat...

    Mercury 7.5 HP Motor Refresh (1969 model year)

    Another Update: I got the lock-out spring installed. I just removed the lock-out lever and was able to insert the spring and then re-install the lever. I needed to get the spring installed before installing the cable and ignition kill switch. Fortunately, I had taken a picture of the...

    Mercury 7.5 HP Motor Refresh (1969 model year)

    I have the lower unit on and did a bit more work connecting the choke lever. There is a wire spring that assists the neutral throttle governor . . . it came off during the disassembly many months back . . . although I'm not sure how it did, because it seems to be nearly impossible to put back...

    Mercury 7.5 HP Motor Refresh (1969 model year)

    More progress . . . here and there. The parts came for the Merc, so I was able to do a few more things. There should be 2 specialized nuts for the steering handle pivot . . . one of the nuts was missing when I dis-assembled it. So, for $15 :eek: :rolleyes: I was able to order one . . . it is...

    Mercury 7.5 HP Motor Refresh (1969 model year)

    I got the bottom cowl and the transom/saddle assembly installed today. I'll be waiting on a few replacement parts before doing more, but it is starting to look like an outboard motor again :)

    Mercury 7.5 HP Motor Refresh (1969 model year)

    I have been trying to sort through the various hardware and fasteners to make sure I get them where they are supposed to go. My bad for not better categorizing during disassembly. I did find 1 or 2 fasteners for the lower cowling that were in the wrong place from a prior re-build, so I got...

    Mercury 7.5 HP Motor Refresh (1969 model year)

    Well, I could not resist doing the first finish coat (black), which I needed to do before staring to put the rest of the motor together. Engine cover/cowl . . . Lower cowl and skirt Transom bracket Powerhead/Drive shaft housing I used Rustoleum Universal Paint/Primer-in-one. (Gloss...

    Mercury 7.5 HP Motor Refresh (1969 model year)

    I spend much of New Year's day doing some painting of the various pieces of the motor (and watching football). Here are the pieces/parts with the Zinc Phosphate primer applied. The primer still seems slightly tacky after about 16 hours. I did apply some heat to help with the...

    Mercury 7.5 HP Motor Refresh (1969 model year)

    New Year's day update . . . Happy 2017 everyone :) I am doing some prep work for painting and continued assembly, taking care of some issues . . . The bottom cowl is 'suspended' from the drive shaft housing using 3 rubberized mounts . . . 2 in the front and 1 in the rear. The front mounts...

    Possible Non-Skid deck solution

    I used 24 oz woven roving to create non-skid areas on my fiberglass dinghy that I made a few year back. 18 oz might be OK too. I did give everything a final coat of gelcoat . . .

    I vote yes

    Keeping in mind that 'we' are the ones that survived . . .

    Mercury 7.5 HP Motor Refresh (1969 model year)

    Snowy Day Update: I have been doing a bit more work on assembling the motor and seem to have run into an issue . . . The ignition assembly is supposed to slide down over the top bearing carrier/cover and have enough play to be able to pivot for the timing advance as governed by the throttle...
