    1988 Mercruiser 3.0L - Random no start on first startup of the day

    Hello All Been a while since I posted. My 1988 Stingray has behaved admirably over the last two seasons, and have not had any issues that I could not quickly resolve. No issues, that is, until last Sunday. Boat in the water for the first start of the day, pump the throttle with shifter...

    Old non-e premixed fuel and what to do with it

    So, I am in the process of completing the reassembly of a 1997 Seadoo GSX with 787 dual carb engine. This ski blew its MAG (front) piston either due to a lean condition (that's what I think after cleaning out the carburetor filters) or from excessive cylinder wall clearance (assessment of...

    Synthetic Grease for top-end reassembly

    Hey folks So, I am attempting my first top-end rebuild on a motor. I have a 1997 Seadoo GTX with the 787 engine that I have had honed, crosshatched, and matched to new pistons. I am getting ready to reassemble everything, and I see in the manual that it calls for "Synthetic Grease" to be used...

    Alpha One shift cable adjustments - adjust to spec, or leave it working correctly?

    Sorry if this is a long read... Last year before the boating season, I had a mechanic replace the lower shift cable due to problems with the outdrive not shifting reliably into neutral (It would stay in forward gear when shifting from forward to neutral sometimes). All last season, while it...

    1995 Seadoo SPX Carburetor needle/seat question

    Hello all So, I found me a project for the winter. I picked up a 1995 Seadoo SPX that had been "Redneck Engineered" some, and was no longer working. The PO decided that the mechanical fuel pump was not working, so he bypassed it and installed an electric fuel pump instead. He subsequently...

    Thanks to all you folks again!

    So, when I stumbled across iboats some number of years ago, I knew absolutely nothing about motors. I've slowly progressed from small two-strokes, to my current I/O 3.0L Mercruiser. Apart from boat engines, though, I have learned enough to attempt repairs on yard equipment, and have managed to...

    70's era 15' Yarcraft yankee project question

    oba97, I use to have a '76 Yarcraft Yankee. The wires, steering, and control cables were indeed run under the helm-side gunnel. What I remember was that there was a heavy-duty cardboard tube set in the foam under the gunnel, and everything ran through there. The PVC idea would be equivalent to...

    Temperature Uniformity on a 3.0L Mercruiser

    So, I posted a thread a while back about concern that my 1988 Mercruiser 3.0L might be getting warmer than normal. In the end I think I attributed it to the lake being unusually warm this year. Well, I finally remembered to take my non-contact thermometer this weekend when I went out. What I...

    Checking Manifold and risers requires new gaskets?

    I probably know the answer to this one, but I'll put it out there in case I am wrong... I have a carbureted Mercruiser 3.0L (Circa 1988). I've noticed the motor is running a little warmer this year than it has in the past. Still within "safe" range (gauge reads about 160-ish where it used to...

    Second Wakeboard

    So, I took the challenge this summer to learn to wakeboard. Not wanting to get too deep equipment and money-wise, I pretty much cheaped out and bought a Hydroslide wakeboard with Suction bindings on e-bay. It was enough for me to learn how to get up, edge across the wake, surface 180s, switch...

    What to use trolling for trout?

    I used to live in Tucson and would spend weekends up in the white mountains trolling for trout in the stocked lakes up there (Reservation Lake and Big Lake come immediately to mind). The absolute, never-fail trolling rig was a set of cowbells, with about 12" of line and a small hook tipped with...

    Shift cable at remote control disintegrated!

    Gaaaah! My internet Fu has failed me. So, went out today on my 1988 Stingray (3.0L Mercruiser/Alpha 1) to get some lake time/learn to wakeboard. Was towing the kids on the tube when one fell off, so I throttle back, into neutral, then try to reverse. No reverse. Heck, no neutral! I had...

    Right battery for my boat

    So, I have a 1988 17.5' Stingray Bowrider with a 3.0L Mercruiser (carbureted). I just got back from the mechanic where he rebuilt my carburetor and replaced my lower shift cable. When I got the boat back he told me that I should think about replacing my battery as it is over 5 yrs old and...

    Seadoo Islandia - What do I need to know?

    Hey all! So I am pondering upgrading from my Stingray 176 Bowrider. Combing different ad sites, a Seadoo Islandia has come up at an attractive price. Its a 22' deck boat. I haven't called the seller yet or seen the boat, so I don't know a thing about condition. According to the spec sheet...

    1988 Mercruiser 3.0L - starting issues. Time for a new battery?

    Hi all So, I have a 1988 Mercruiser 3.0L 135 HP I/O with some strange or unexpected behavior when starting up. If the boat has been sitting for a time (usually about 6 days, Sunday to Saturday), If I turn the key from the off position to start, I get nothing. No clicking, no attempt to engage...

    Lower unit service perhaps done incorrectly, need advice

    Okay, so this was my first attempt at doing service on my Alpha 1 outdrive. I thought I had done everything correctly (waterpump replaced, remembered the quad ring, greased u-joint bearings, checked the gimbal bearing for function, etc), used a new gasket on the bell housing, reassembled the...

    Which is the right grease? -one step beyond Bond-o's "any grease is better than none"

    Which is the right grease? -one step beyond Bond-o's "any grease is better than none" I have an Alpha one (first generation) with Mercruiser 3.0L 140 HP on my boat. I'm doing my first full-on "pull the drive inspect everything" service on it. So far I've pulled the drive, checked alignment...

    Regular Marine starting battery on a jet ski?

    Hello all So, I now have a winter project to keep me busy while waiting for the lake to warm back up to usable temperatures. I was given a 1989 Kawasaki 650 TS supposedly in working condition. The battery has been removed, so I can't verify that it will crank. I wanted to to basic checks on...

    Fuel in Carburetors through winter storage

    Hey folks So, even though its still boating weather here in Georgia, nighttime temps are staying in the 50s, and I suspect the lake will be too cold for my family fairly soon. I'll get a couple of fishing trips in, but I suspect I'll be winterizing the boat in the next 60 days or so. This...
