    XD50 vs XD100 in mid 90s 3 cyl

    with that being the case you might want to look into Pennzoil Premium Plus as well. I buy PPP at my local auto parts store for $18 per gallon. PPP is my oil of choice if I can’t get a good deal on XD 50. I see no difference between PPP and XD performance wise. Ie smoke, smell, etc. PPP...

    2017 yamaha 300hp 4stroke stalls on slow acceleration or deceleration

    Moving the throttle is common to both situations. I would check for a flakey shift switch or whatever mechanism they use today. I would also check to see if you didn’t have any loose or chafed wires in the throttle

    XD50 vs XD100 in mid 90s 3 cyl

    I buy XD 50 for $30 per gallon on case lots. Would love to find XD 100 for $15 a gallon

    1999 Caravelle VDO Speedometer

    Are you sure that assembly went to the speedometer? Upon closer inspection it looks like a transducer with a paddle wheel. Are you sure there wasn’t a fish finder onboard at one time? How many pins in the connector? Be easier and probably cheap to just replace with a GPS Speedo of the...

    Autopilot set-up for Alpha 1 Gen 1 outdrive

    I troll on AP with my main motor at 2-7 knots. Quite often under less than ideal conditions. No way I could manage the trolling spreads I pull w/o a bit of help. Unfortunately, none of the inexpensive APs will do very well when push comes to shove. A $1,200 Chart plotter add-on isn’t going to...

    Transducers and Hull Thicknesses

    There is no limitation on hull thickness per say but you must install the transducer in an area with nothing but solid fiberglas between the puck and the water. Even voids in the fiberglass will cause problems. To test your proposed installation site: Put transducer in a ziplock bag full of...

    Experience of Turning Point props? Prop failures?

    Not saying it’s not a casting flaw but cavitation (prop burn) manifests, looks like air bubbles as well.

    Engine hour meter and depth finder

    Pretty sure you download hours and rpm from the ECU. Perform PM on an annual basis and the need for said meter goes away. Do you want digital depth (gauge) or a chart plotter/fish finder? Budget?

    Power Steering high pressure hose coating flaking off

    You can tell from the picture that the hose jacket is crazing, the telltale sign of dry rot. Like anything else hoses deteriorate with age. Never use hose near or over 10 years from the date of purchase or hose that is past the manufacturer’s use by date

    4.3 blows 15a fuse when you throttle up

    You have a short to ground in a “wet” location. The bilge pump circuit would be my first guess.

    Radio turning off at certain volume

    The ground is just as important as the positive in a DC circuit.

    Adjusting Trim Tab

    The tab simply creates drag opposite prop rotation. It’s only effective for the speed and trim you set it for. Works great for a motor w/o trim and tilt. You can dynamically counter prop torque by adjusting your trim angle. Trim down increase torque steer, trim out far enough and the prop...

    Smartcraft data bus fuse

    Looking at the harness docs, I’m willing to bet the fuse blowing at a certain rpm is a coincidence. Data communications use mA of power but documentation shows the harness also supplies a 15 amp, key switch controlled “accessories” power harness through a 10 pin connector. Who knows what’s...

    Power Steering high pressure hose coating flaking off

    The hose is shot (dry rotted) and needs replaced. The other hose in the picture looks bad as well

    How to change hoses on deck drains

    Hard to give advise with no idea what boat your working on, the type of drain or how the hoses are routed.

    a different stereo/dual switch question

    Goggle the make and model of your switch. Look at the specification sheet. Should tell you everything you need to know.

    a different stereo/dual switch question

    Connect your new wire to the accessories terminal on the back of the off/on/both switch. Power will stay on as long as the switch is not turned off. Most “modern” switches are “make before break” meaning you can switch between 1&2 with the engine running. If it’s not a “make before break”...

    Adjusting Trim Tab

    A boat will pull hard to the right if not trimmed properly as well. If your running neutral trim or lower, trim up a bit and see if it dissipates at all.

    Wheel bearings full of water

    Both are made of steel. Both have the same rate of thermal expansion........0.0000072“ per degree F. It’s a non-issue. Installed properly, they work quite well actually. I’ve never had one leak on me in the 20+ years I’ve had EZ lube hubs. The bigger issue is the increased ( ~ 2 psi)...
