    Play on propeller shaft

    Thanks, both. Suggestions done. In and out prop movement is 1/8 inch. No side to side movement. Rubber hub looks good, the washer looks new, prop retorqued to 55 lbs. Movement unchanged. It's the shaft that's moving in and springing back out, not the prop and hardware. Assuming that this is...

    Play on propeller shaft

    Hello. The engine is a 2023 Merc 150 with a Solas prop - 105 hours on the engine, 50 hours on the prop and prop hardware. Just noticed that the prop can be shifted in and out about 1/8 - 1/4 inch on the shaft. Resting state is out, prop can be pushed in, but then moves back out and feels...

    Question about 2 batteries, 2 chargers, and switches

    Not ideal setup but simple and good enough for the particular boat: two AGM batteries, positive terminals connecting to a 1/2/1&2/OFF switch, and on the other side, to a common (one for both batteries) ON/OFF ground switch. Question— I have two chargers and would like to use both - one per...

    Advancements in peddle boats?

    Quite a few kayak manufacturers make pedal kayaks these day. I own two. They can be pedaled or paddled or both at the same time. Forward or reverse. If the pedal boat doesn’t work out, look into a pedal fishing kayak. They’re broad platform kayaks (you sit on the hull, not in it), and they’re...

    Variance in water pressure

    I have a 2022 Mercury 150 four stroke with 72 hours. A friend with more experience with powerboats (I've been a sailor and kayaker mostly) has expressed concern about the variance in water pressure. At idle, water pressure holds steady at 6 psi. At cruising speed on plane, water pressure varies...

    Parallel battery specs

    Apologies for disappearing from my own thread; unexpected road trip. I appreciate the responses. I didn't think the "same brand" advice - the question I had originally asked - was correct, but due diligence.... That said, I found a local going-out-of-business sale and snagged another Optima...

    Parallel battery specs

    Hello. I'm adding a second battery to a boat with an outboard (2022 Mercury 150 4S). The two batteries will be wired in parallel. The first battery came with the boat and outboard, all of which are six months old and have 30 hours of use. That battery - not my choice - is an Optima Blue Top...

    RPM range question

    Ya, we bought this - our second boat, our other one is a CC - for the wife. I'll say, however, that I've quickly learned to appreciate being comfortably "indoors" in the winter and weather, and the stability, too. Nice to be able to take this boat from the island into town and do some shopping...

    RPM range question

    4400 lbs, 18 degree deadrise, 45 gallon main fuel tank (12 gallon aux), midships pilot house for good balance, marketed as an inshore pocket cruiser, a role performed well in the northern GOM and associated bays and sounds. A 9 foot beam, which might explain some things. Overall, a good, special...

    RPM range question

    Dec. 2022 manuf date; height is spot-on by the operating position of the cavitation plate; SC1000, an analog fuel gauge, and a NMEA 2000 connection to a Garmin display.

    RPM range question

    An update: Tach and engine particulars verified. The propeller was re-pitched from 15 to 13 by a local prop shop that has done this kind of work for 30 years. About a quarter inch was shaved from the diameter and the cup was maintained. WOT on the boat is now just under 5400 rpm and most of...

    RPM range question

    I posted my response before I read yours. This answers some additional questions. The four blade prop is an interesting suggestion. Thanks.

    RPM range question

    The boat is a Jeanneau NC 695 "Weekender". Built in France, there are a huge number of them in Europe, Asia and NZ/Australia, where they're known as the Merry Fisher line. Jeanneau rates the boat at 175 HP max; most sold in North America come with a 150 HP Mercury or Yamaha; in Australia a 175...
