    Lookin' for documentation,.....

    Yes. At least as far as I know and have seen in the wild. Mercruiser never sold a RH rotation engine as a sterndrive package. All sterndrive oem packages are LH rotation engines. Can't say as for any Lake X trails but as far as general public market availability your looking at LH rotation...

    What causes this knocking tapping sound?

    Wondering along with being up/down if the drive is turned hard over port/stbd? On the trailer, muffs, no load? In the water under load? Could be any number of causes from having the drive tilted up to detonation

    Water in upper unit

    There is a plastic fitting in the bell housing. It's half of the gear lube passage that mates with the drive ball valve to complete the monitor system between the drive and gear lube monitor in the engine compartment The gasket has a partial cured sealant that surrounds the valve assy when the...

    Testing transom assembly for leaks

    The transom assy is a stand alone component of the sterndrive package. Having no engine installed won't affect your test. I'm guessing you have the exhaust y pipe in place and the water passage barb blocked off? You could still use the trim system without the engine in place. Connect the trim...

    Need help with Rotary Steering Cable!

    The tiller arm is in the upper right area of the pic. The black arm.with the continuity strap attached to the inner transom plate. Remove the pin that attaches it to the PS actuator. This will allow you to swing the drive side to side easily

    Water in upper unit

    Yes, that is the shoulder area for the water passage o ring. Only way water would get near/in the bellows is when the engine is running and leaking water seeps into the bell housing/drive housing cavity. After that water would have to seep past the quad ring forward of the drive...

    Throttle lever issues. Replace or repair

    Probably not going to find any replacement parts save for finding a complete remote assy of the same vintage in good shape. If you can source a copy of the mercury remote controls manual you can see a schematic of your remote. Disassemble and see if it's repairable/needs parts replaced There...

    5.0 mercruiser won’t idle under 1100(ish) rpm’s

    As long as the ignition/engine mechanical is sound an experienced marine mechanic would be able to remove that carburetor, dismantle, clean, install new parts, assemble, install, adjust and have the engine running well in about an hour or two. Probably one of if not the simplest carbs on a...

    Need help with Rotary Steering Cable!

    30 year old steering cable is definitely #1 suspect of stiff steering regardless of radius of bends. The component pictured with the hoses attached is the power steering actuator. Fluid quality/level is inspected at the pump located at the front of the engine. Unless the system is low on fluid...

    2007 Mercruiser 4.3 w/ cracked block

    Thats most likely an L35 and utilized vortec heads. I'd guess it'd be fine for the intake off the cracked block but as stated earlier you need to ensure the intake wasn't also freeze damaged

    Need help with Rotary Steering Cable!

    9 (or more if possible) times out of 10 the cause of stiff steering is the cable. Often times the tight bends at the helm/hull and in the corner of the hull/transom as the cable routes to the transom assy causes wear/chafing in the sheathing. Material from the sheathing builds up and causes...

    1980 ChrisCraft 170SS freshwater pump

    Yes. Delco EST/HEI. Commonly found on many oem mercruiser, volvo and crusader GM based engines however the coil is always divorced from the distributor. The ignition module is mounted on the distributor plate under the reluctor wheel/sensor assy The coil on the distributor cap is a red flag for...

    O-Ring Re-use and/or part numbers

    Can't help you with specific part names or installation techniques but if you're having trouble sourcing parts/info online it's in your best interest to contact a local volvo repair shop/dealer. By dealer I dont mean a boat dealership, find a repair shop that is volvo certified, preferably...

    Inner transom plate

    If it's a 4.3 I'm guessing the boat is a smaller runabout? If so the 5 (ish) hour estimate/flat rate is close. Only reason a shop would stray from flat rate on a job like that would be access issues involving removal of rear bench, engine cover, side panels, etc... Once the drive and motor...

    Velvet drive dipstick tool
