    grumman repaint

    If I knew the manufacturer of the base coat, I would also most likely know for certain whether or not it is zinc chromate :) I'm going to need to guess. Any thoughts on the probability of "safe" options? Would it help if I took and posted some photos? I don't mind the effort of doing the top...

    grumman repaint

    The way this is peeling, it doesn't look like removal will be much of a problem. Maybe the painter didn't know that there is supposed to be an intermediate coat. Based on color and adhestion to the aluminum, how confident would you be that this really is zinc chromate? Any way to actually test a...

    grumman repaint

    A few months ago, I acquired a 1973 Grumman 17.5 squareback canoe in marvelous condition. No leaks, and I cannot even find any of the small scratches and dents that are nearly always present on these boats. It does, however, have one serious cosmetic issue. Quite a few years ago, the original...

    better refueling for gravity fed outboard

    Hi. I previously had a 16' aluminum transom canoe (Michicraft) with a 3 HP Gamefisher (Tohatsu) OB that I liked very much. I replaced that with a 16' Sea Nymph semi-V and 25 HP OMC. For my solo use the replacement boat has proven far more trouble than it's worth (another story,) so I'm planning...

    1976 25 HP - can I invert for maintenance?

    Hi. I'm about to replace lower unit seals on my 1975 25 HP Evinrude. The lower unit attachment bolts face down (blind bolt holes facing upwards.) My biggest concern right now is snapping off the bolt heads, so I want as much control as possible over applied torque. Working from "under" the bolt...

    1990 & 1976 OMC 25HP SS - part interchange

    I currently have a 1976 25HP Evinrude short shaft motor. Good compression, runs well, but needs lower unit seal replacement, which I'm about to attempt. I found the same basic motor branded Johnson vintage 1990 offered for sale at a reasonable price, ad claims good running condition. I was...

    Extended shift handle 1976 25 HP

    Hello. I have a 25602E Evinrude manual everything (which is how I like it for this boat.) I have no trouble reaching the tiller and throttle from my seating position, but the shift lever is a bit of a stretch (opposite side of the motor.) It isn't critical, but I will have a long reverse at my...

    1976 25 HP Evinrude issues advice request

    Hello. I have a 1976 Evinrude 25 (2 cylinder 2 stroke) pull start motor that I purchased last May. At that time the PO ran it for me in a tank for about 10 minutes: started on 2nd pull, seemed to idle well, with no obvious issues. The motor has been living on a stand, covered, for the past 4...

    Quick change fuel tank set-up

    I have a 1972 16' Sea Nymph semi-V with a 1976 25 HP short shaft Evinrude. I would like to maintain 2 on-board low-profile 6 gallon portable plastic fuel tanks sharing a single fuel supply hose and suction bulb in such a way that I can quickly swap tanks when one becomes empty. The typical...

    fuel lines, gas tanks, & EPA compliance

    I need to purchase a new fuel line for my 1976 Evinrude 25 HP motor. I have 6 gallon plastic tank and complete hook-up originally used for a 6 HP Fisherman of about the same vintage, but the siphon bulb is shot. My inclination is to reuse the tank and replace the entire line, adding a fuel...

    25 HP Evinrude model 25652E routine maintenance items

    I have acquired a 25 HP Evinrude short-shaft 2-stroke 2-cylinder tiller-steer pull-start motor to repower my 1972 Sea Nymph Coho 16. Model is 25652E, s/n is E0005739, which seems to date it to about 1976. Motor starts easily and appears to run well. PO claims he purchased last July and used it <...

    transom restoration

    Finally got around to this. As mentioned in an earlier thread, the previous owner of my 1973 Sea Nymph had done a half-a$$ transom extension because he had been given a long shaft 40 (?) HP Mercury outboard for free. My single misgiving about acquiring this boat was in regard to what kind of...

    owner's manual for 16R40

    Hi, folks. Anyone know where I can download or purchase an owner's manual for my 1973 Coho 16, or any 16R40 deep vee SN of similar vintage? As an open aluminum utility, most things about the boat are quite obvious, but there are a few of details that I'd like to learn more details about from the...

    Coho 16

    Hi, folks. Just bought a 1973 16R72 (I assume the "72" is correct as I measured an actual 71-1/2 in) badged " Coho 16" with a Tee-Nee trailer of the same vintage and a 40 HP 2-stroke 2 cylinder Mercury. The alleged story on the boat and trailer is that the original owner purchased both new in...

    Which motor is this (s/n confusion)?

    I recently bought an 1973 Sea Nymph 16R72 deep-V equipped with a 2 cylinder 2-stroke Merc that is badged "40 HP Thunderbolt". The s/n on the motor tag is "OB272613". Those 8 characters are engraved or relief-stamped. There is space for a 9th character, but nothing appears in that space...
