    Shoreline Trailer Highlander Series

    Eastern marine has a whole lot of trailer parts. They may have shorelander stuff, or at least you should be able to match up some parts. What is it you need?

    1996 Evinrude OMC VRO Intermittent No Spark

    Black/yellow wire is ign killer. If it is grounded anywhere, it will kill the spark. I suspect it has rubbed thru the insulation somewhere. Disconnect the ign killer wire at the powerpack, and see if you have good, permanent spark. Be prepared to kill motor with choke during this test. If...

    Spun hub or lower unit problem?

    Gee, I thought you said it was at the limit of it's adjustment. Control boxes should be readily available.

    Process for changing boat trailers?

    Gee, I dropped my speedboat on the ground, the motor tilted up enough. I then backed up the new trailer and d/c it from the car and winched it on. The key is to allow the trailer to go under the boat, vs dragging the boat. It also allows the tongue to go high. Of course, my speedboat is...

    Spun hub or lower unit problem?

    Some of the older control cables have a screw clamp that holds the end on. If you have that, you may be able to loosen the clamp and move the end to shorten the cable a bit. Post a picture of the engine end of the cable.

    '85 Merc 50HP 2-Stroke - Rich/Lean Adjustment

    No, the engine must be in gear, with a prop installed to set the carbs. On the water is the best for those of us without a professional test tank. The design of those plugs look a bit different than what I expected, and I have worked with a lot of BUHW spark plugs. I don't remember the...

    Ever wonder where all the hurricane and storm surge boats wind up ?

    When we had Hurricane Sandy here in NJ, many boats were liberated from their blocks at various marinas. Nearly every neighbor had one in his yard after the storm. The marina came to collect them eventually. I was lucky enough (sic) to get my neighbors 20 footer w/ Yammie 150. It went from...

    Lucky Day

    Unfortunately, PTT motors do fail. Here on the salt pond, they can rust thru the outer casing. At least that is what happened to my Merc PTT motor (likely made by ARCO), and the boat lived on a lift. My Johnnyrude OEM PTT motor from '98 is just fine, and that lives in the water 7 mos. a...

    '85 Merc 50HP 2-Stroke - Rich/Lean Adjustment

    Most Mercs use a gas screw, vs an air screw. That means that tightening the screw leans out the mixture. Usually you start at 1-1/2 turns open and adjust from there under load in water, at idle, with a warm engine. Normally you need to richen them up from there a bit to allow acceleration...

    Hard steering.

    Something else that can help is to figure out where the steering is corroded. Usually it is the top bushing of the swivel shaft. If you can get some grease into the offending bushing, it can loosen up. If the top bushing needs grease, tilt the motor up fully. I then use a rope around the...

    Steering stiff

    Is the steering stiff underway, standing still or both? If standing still is hard to steer, disconnect the steering cable at the engine and retest. You need to isolate the stiffness to the cable, steering rod or motor pivot. Those steering rods often get corroded, although that usually...

    Alpha1 and Alpha1 Gen II U joints

    Gee, Years ago I took my old MerCruiser Alpha I Gen I u joints to my local auto parts shop. They cost about $50 ea in those days. They matched 'em up with u joints they had is stock for $12 ea. The auto u joints had larger, but less roller bearings than the OEMs, but they lasted until I sold...

    Outboard motor upgrade?

    I saw a hydrofoil for a pontoon boat. It is supposed to lift 'em a bit when cruising. They never claimed an increase in speed, but did claim fuel savings.

    CLR salt removal experiment

    I found some scale build up on my '93, which I run exclusively in salt water and never flush. I pulled the gearcase and thermostats and pumped some 50/50 RdyLyme and water thru the motor using the water tube. I used a sump pump to circulate the descaler for 4 hours. Unfortunately I could only...

    How to test shift interrupter on a Mercruiser?

    Gee, you might tell us the engine and year. Can't you simply disconnect the ground wire to the interrupter?

    Spun hub or lower unit problem?

    Agreed, sounds like the hub. If the prop is newer and has the modular hub, it will be easy to replace. If older with the pressed in hub, you need to find a prop shop, or buy a new prop and modular hub.
