    1973 starcraft ss restore in progress

    Great transformation! I've got two 16' supersports (74 and 84) ... one of them needs all the wood replaced. You are giving me some great ideas. Thanks!

    2000 Johnson 70 j70plsis

    Thanks for the description. I picked up this entire outboard and controls for parts, so I'm not sure if I'll have the PH fixed, hold it, or sell it. Maybe I'll drop it off at a machine shop and have it assessed.

    2000 Johnson 70 j70plsis

    When Faztbullet posted the comment about pinning the cylinder, I searched and found that item. Looking again, that part is in the exhaust housing. Your assessment is what I was also thinking.

    2000 Johnson 70 j70plsis

    Where does the pin go? I found OMC part 350943 described as pin (sleeve). What do you think caused that groove?

    2000 Johnson 70 j70plsis

    I just picked up a 2000 Johnson 70 hp outboard from Marketplace. The seller was very clear, it overheated and one cylinder sleeve has rotated out of position. That's OK, I bought a short block the day before and wanted this for parts anyway. So, I decided to take it apart and split the block to...

    Compression too high?

    Syracuse NY ... also a very short boating season. I've pretty much decided on skipping this one .... but does anyone have a comment as to compression? How much is too much?

    Compression too high?

    Sorry, my bad. '72 Rude on a '74 Starcraft Supersport 16'.

    Compression too high?

    Yeah, missed a couple decent deals. Most J70 motors are around $2000 - $2500 in this generation. There's one or two guys locally that seem to buy up the decent used OBs to resell. I've seen some parts OBs for about $1200-$1800 but those are around 3-5 hours away. I'm not in a hurry, I've got a...

    Compression too high?

    I've considered this. The PH isn't salty but it had evidence of overheating. Maybe the VRO failed and it ran oil-starved. One of the crank journals is worn down, that piston was cracked, the cylinders unsurprisingly scored. When I started adding up costs a used PH in good condition sounded like...

    Compression too high?

    That's my thought, skeptical ... it's a fair price, $1K shipped from Fl. Cheaper than most used complete outboards with this PH. The seller appears to be an outboard service business. Priced as-is but since he put it out there as 155 even compression it can be considered a guarantee. Could be...

    Compression too high?

    I'm looking at a '97 E70TLE powerhead to replace my failed '01 J70PLSIS powerhead. My concern is their purported compression is 155 on all three cylinders. Is that high for a used PH? I don't have the compression specs for that PH but most info I've found seems to put good compression at about...

    1981 Mercury 75hp water pump question

    Here is a picture of that area on the pump housing that was removed. You can see the imprint of that raised area and the scraps of gasket.. The earlier picture I posted of a new OEM pump base was to show there is no apparent indent to allow for this "step". The gasket is flat, so no allowance...

    1981 Mercury 75hp water pump question

    I would like to know what that area is. One more marked up picture to be absolutely clear.

    1981 Mercury 75hp water pump question

    @racerone @Chris1956 Any idea why that "protrusion" exists near the bolt where the "paper" gasket will be laid? The pump that came out has marks from that raised area. It would seem to me that without an absolutely flat mating surface the gasket isn't going to do it's job, or worse it slightly...

    Sorry, I thought I posted the SN: 5755418 ... This is the raised area pointed out ...

    1981 Mercury 75hp water pump question

    My apologies, 70hp. Sn is correct. Not the o ring groove, the flat surface that will have a "paper" gasket under the flat surface of the pump base. Enlarge the first picture and you'll see the raised area in front of the bolt. That raised section looks like it will hold the base slightly off the...

    1981 Mercury 75hp water pump question

    I'm replacing the water pump in my 81 75hp mercury ... while cleaning up the base gasket that sits on the top of the gear housing I found that there is a ridged section. It looks like the water pump base should be notched but it isn't, neither is the old one nor in the pictures I've found online...

    Inherited new boat. Unsure what it is exactly

    Sorry, was offline getting ready for a camping trip. It's just painted plywood. The snap cover I've seen is just a piece of vinyl with snaps. Should keep the girls out.

    Inherited new boat. Unsure what it is exactly

    Congrats on the "new" boat. I have two SS 160's ... a 1974 that used to have those double doors and an 84 that has a plywood door (see the pic) on a piano hinge that flips up. I removed the double doors from the 74 because it was a pain to get in there with the gas tanks, batteries, bilge pump...

    84 SS 160

    Started right up and ran nice for about a minute or so. After sitting since 2014 it likely needs a fuel pump diaphragm kit. Waiting on that now. Also ordered a water pump kit while I'm at it. Power trim is working well now after spraying the limit switch with electronic cleaner. I'll be...
