    First Impeller Job, 1987 OMC Cobra Standard

    First time R&R'ing an impeller. (OMC did make it simple on the Cobra). A 3/8" six point socket and rachet, and six screws later ,and a couple minutes, the impeller was out. See photos. The photo with the impeller still in the housing shows most of the blades going one way, and then (3) of them...

    What Is The End Play On An OMC Cobra Prop Shaft?

    The spec in question is for a 1987 OMC Cobra Standard with a 2.3L Ford (rubber band). I just spent an hour searching the OMC manual and this forum and can't find that spec. (I may have missed it) Putting a dial guage indicator on the end of the prop shaft, what should the end play be for...

    Is EP 90, GL-4 Okay To Use In A 1987 Cobra Outdrive?

    I recently drained and refilled the Cobra (standard with 2.3L Ford) outdrive with EP 90, GL-4 rated gear lube. (EP = Extreme Pressure). Rereading the OMC specs, I realised it calls for a GL-5 rated lube. I see nothing about an EP rating, either. The boat is not sea-worthy, so it hasn't been to...

    Splash-Well Battery Cable Grommet

    On my 1996 1700 LS, there is a nylon-like grommet going thru the port side of the splash-well. The battery cable is routed thru this grommet. See attached photo. There is no seal or boot, and there is quite a bit of open space around the cable. Is there suppose to be a seal or boot to keep...

    1987 Baretta SS, OMC 2.3L Cobra

    My original intent was (still is) to buy a goode olde tri-hull (15' -16') for a 90 HP Chrysler O/B I have. I see hulls advertised at these salvage lots for $50 to $300. I've been to a few and have seen a couple half decent ones with solid floors and transom (less work). These hulls don't come...

    OMC Cobra 2.3L 1987, Outdrive Test On Muffs

    This is my first I/O. I'm going thru the engine and outdrive to see if it's any good. The engine has checked out fine. 150 -155 lbs. compression on all cylinders (warm). 55 psi oil pressure (warm). No water in the oil. The engine runs smooth and starts well and idles at 800 RPM in neutral...

    Is V-P A Subsidiary Of Volvo?

    The reason I ask is there's a news article that Ford (who use to own Volvo) has sold Volvo to China. If V-P is in the deal, I wonder what we can expect of the future of V-P, parts, durability, etc.? Here's the article I saw: China buys Volvo from Ford Source: RTT News URL Source...

    Speaker Installaton Problem

    I installed a Dual brand AM/FM/CD/MP3/USB/AUX receiver #MXD662B from West Marine in my Bayliner yesterday. It came with (2) round speakers advertised as 6.5" in size. The receiver installation went well. The speakers are a problem. The Bayliner came with (2) 4.5" round speakers and the 6.5"...

    Is This A Normal Amount Of Rust?

    A couple months ago I bought a good trailer. A 1987 Baretta 16' boat came with it free. The boat has a Ford 2.3 Liter Cobra I/O. The hour meter says 95 hours (may or may not be true), but all the instruments are in very good condition and work. I ran it on the muffs yesterday. I noticed it was...

    Do 90 HP Chryslers Have A Telltale?

    I recently got my old 1974 90 HP (907HA) running. Haven't changed the impeller yet. That's next. While running it on the engine stand, on muffs, the exhaust snout has a good amount of water coming out of it. On the starboard side of the lower end, just below and forward of the vent plug (not...

    Why Does The Outdrive Feel Solid When The Transom Is Rotted?

    I recently bought a good trailer. A 1987 Baretta Super Sport (16') came with it. From the inside, the transom is obviously rotted and soft spots in the floor. From the outside, the transom looks great. No stress cracks anywhere. With the drive in up position, I can lift the back end of the...

    Is This A Problem, Or Normal?

    RE: 1975 Chrysler 90 HP 3-cylinder, Motorola ignition. With the spark plugs out, carbs and intake off of the motor, motor in forward, neutral or reverse (doesn't seem to matter), I rotate the motor, using a socket on the flywheel nut, and can feel (12) places in one revolution where there is a...

    Will It Damage the OMC Cobra Components To Dry Shift?

    I have a 1987 OMC Cobra 2.3 Liter. Will it damage any of the components to "dry shift" it? Meaning, with engine off, boat on a trailer, moving the throttle lever all the way forward and/or all the way in reverse. Components being the throttle lever, control, cables, lower end gears, dogs...

    I'm Having Trouble ID'ing A SS Prop

    I bought a locked up lower end from a 1991 Force 150. It came with a stainless steel prop in good condition. $25. The part number on the hub says "384702". A number on the outside of the hub says "K1531". The prop is 12 3/4" X 21P. I ran some searches and got nothing on the K1531 number...
