    Engine smell in cabin when boat is tarped for the week (350 i/o)

    Same here. I've had it almost 20 years. Very few repairs to the drive and transom mount. I bought the special OMC tools to set up the shift cable and taught myself to do it in an afternoon. It shifts very well and has been very little trouble. I did do a top end overhaul on the 4.3 V6 4 years...

    Just won't start anymore

    Agreed I'd take out each fuse make sure they are not oxidized, and look carefully at all battery terminals and connections including those at the starter solenoid and engine ground stud. Make sure that the large cannon connector is not loose that is a common source of intermittent electrical...

    Engine smell in cabin when boat is tarped for the week (350 i/o)

    How do your fuel lines look/feel? They can be cracked and not actually leak liquid fuel but can leak vapor. Looks like you have an OMC Cobra.

    My boat in saltwater

    Based on my experience with raw water cooling (admittedly limited to one boat) I think you can get 15 years of pretty trouble free engine life in salt water. After that what happens depends on maintenance habits. When I took apart the top end of my old engine in 2017 it had been used in salt...

    Advise you try to fine a wiring diagram for your model this will help with tracking down where the problem is. Start with checking the battery connections both at the battery and at the starter solenoid & engine ground (stud on bell housing behind starboard exhaust hoses). With the battery do...

    My boat in saltwater

    Agreed the spindle lube/super lube system works well because with frequent greasing you can see if the grease has gotten contaminated with water. It’s tough to make trailer brakes last in salt water if you are a trailer boater and put the trailer in the water every time you use the boat. In that...

    My boat in saltwater

    Next spring I promise I will post pix of Northport & Huntington NY as well as the harbor behind my house here in Long Island so you can see the hundreds of boats that survive and are used all season long here. My boat has been out on the mooring for 20 seasons. It still has the original outdrive...

    My boat in saltwater

    Yep Scotts right change both of those cables use marine cables and no wingnuts or those auto parts store clamps that allow corrosion to travel up the cable. On an important but unrelated to your question….if that boat has wood cored decks I would get rid of that carpet and have the deck re...

    My boat in saltwater

    Mines been salt water for over 20 years! Moored in it as a matter of fact. In 100% salt water use we have certain maintenance rituals that must be followed for the boat to last. But in your case regular flushing will be fine. The boat will be fine. The trailer looks galvanized so that is much...

    4.3 Chevy

    Started with this.... then bought a set of these: And put it all back together: Added a center riser exhaust conversion while I was at it, since the old OMC one piece batwings (same idea as the Merc foghorns) were long since NLA...

    Removed the Wrong Screw

    for a complete usable Cobra, $900 to $1200 or so. When I was thinking of converting it over to a Volvo SX the best prices on those I could find were $3500 and then I still had to buy other parts to make it work like the pivot housing, raw water pump, etc. So after all was said and done, to do a...

    Intake choice

    Based on the kit I have I think you have to remove it because the bracket for the conversion fits where the spring used to be; at least it does on the small block. You have a big block so your need to go research that

    Removed the Wrong Screw

    I think boats today while harder to service seem to be better built vs the older wood core/fiberglass construction. My neighbor has a 2005 Key West 2020 DC with a Yamaha 150 and the boat and structure look nearly new. Fully foam filled so it is also safer than older boats. She's owned it since...

    4.3 Chevy

    If the engine did not overheat, the likelihood of a blown HG is quite low. Sounds like you got water in the oil because the plug was out, mechanic concluded it was from bad one piece V6 manifolds (could be true but in this case could also NOT be true) so he replaced those. However some of the...

    that's a Merc number, if you used a Merc rebuild kit that # should work... look at this pic, the original Rochester carb # is circled in white.... having the original Rochester # enables you to get a better kit from Cliff's.

    Removed the Wrong Screw

    Well Bruce I guess our experience was different then. Maybe because my former mechanics (since retired) were able to set it up perfectly right after I bought this boat in 2002. They set up the shift linkage, replaced some leaky trim lines and a bearing carrier that caused a leak. After that it...

    Removed the Wrong Screw

    Or install it with Red Loctite lol. When this gets removed by mistake they just fall in the water passage that leads from the impeller housing. So if you pull the drive you just tilt it so the retaining plate falls out. No biggie. Still running my original Cobra 33 years old has needed next to...

    Frozen Prop on SX-M Duoprop, Seeking Advice

    Doesn’t look like the PO ever greased it. I’ve been using Evinrude triple guard grease on driveshaft splines and prop shaft splines for years with no problems. Even after 6 months being moored in salt water the prop just about falls off the shaft. Great stuff!

    take a look at Cliff's high performance q-jet site, his rebuild kits are very nice plus he has the better accel pumps, and other better quality parts. Fast shipping and good customer service. Quadrajetparts.com is also good for whatever you can't get from Cliff's. A clean and properly rebuilt...
