BOAT PROPELLER PITCH EASY EXPLAINED
Understanding the Pitch of the Propeller and Its Impact on Boat Performance.
Discover how the propeller pitch affects boat performance in this explanatory video. The propeller pitch is the theoretical distance it travels in one complete revolution. A higher pitch can increase the boat's speed, but it may also require more engine power and affect acceleration. Additionally, we explore why the effective pitch in water is approximately 85% of the theoretical pitch due to factors such as resistance and slippage.

Understanding Cavitation and Ventilation in Boat Propellers. Cavitation and ventilation are often confused but are crucial phenomena affecting boat propellers' performance.

    I just bought a boat. It came with 2 motors. A 175hp and a 10hp. I have no idea how to operate a boat. It's set up for walleye fishing in the great lakes. It also came with 2 trolling motors and about $6k in fishing tackle. I bought it to help a friend of mines wife pay for his funeral. It's a ranger Cherokee. Looks like it came off the showroom floor. Immaculate shape. Now I'm trying to learn to operate it. I just brought it home from south Dakota to Texas. I can find all kinds of classes online for boater education. But nowhere to actually learn by operating the boat. So looks like I'll have to haul it to Oklahoma so another friend will teach me hands on how to operate it. He's familiar with the boat and has been out on it many times. So looks like I'll learn on lake texoma while chasing striper

      It's funny that I'm a lot/little intimidated by this. I mean by the time I was 6yrs old I could operate a tractor on the farm and ride horses. And by 10yrs old I was breaking horses and working cattle. And even bull riding and bronc riding in rodeos by 13yrs old through 25. Never felt intimidated. I always felt in control. Been on probably 40 boats with other people yet never operated one with exception of a 14 ft jon boat with a 10hp tiller motor .

    Stern Drive shows an owners inexperience boating. Do not buy a stern drive. Either by an outboard, or an inboard. No one is going to buy a boat on purpose as a stern drive. Also, no one‘s going to buy a four winns hull either. But anyone that has a stern drive typically, specially associated with the bow rider, is an inexperienced and novice boat owner has anybody with experience would buy neither. Get an outboard

    For a fishing boat you definitely don’t want a stern drive if it’s not offshore fishing. There’s just no arguing that you aren’t happy crawling around in a few feet of water with a stern drive. You simply can’t pull it up enough to avoid damage while you can with an outboard. An outboard if left unlocked will ride up and over if you touch bottom. Sterndrive ain’t goin nowhere . In short you just shouldn’t go in shallows with a stern drive with it running.

  • @dugnology

    for small pleasure boats, outboards today are leaps better than even 10 years ago. The problem with stern drives is the number of critical failure modes. We have muskrats on our lake, and they like to chew rubber. Not an issue with an outboard. With a stern-drive, there are multiple bellows that are just waiting to be chewed up. Your boat will sink. There is also the added complexity of the tilt mechanisms.

    • @marcseclecticstuff9497
      @marcseclecticstuff9497 Před měsícem

      If your bilge pump is working, the boat won't sink, not that much water comes into the boat. I had my bellows fail on in the middle of a 2 week trip last year. It was a non-issue, the bilge was only kicking in once maybe twice an hour. The only bellows that matters is the driveshaft up on top and pretty difficult for a critter to get to. If you leave the drive down, there's no way for them to get to it, it's blocked by the drive. I've always had I/O's, both Volvo and Mercruisers, and always done all the repairs myself as they aren't difficult. One advantage of I/O's not mentioned here is parts are a lot less expensive since many are common car parts. Sure, there's a few that are marine specific like the starters & alternators, but if you break down in the middle of a trip, you can just run to the local auto parts store and get what you need to get back home. They won't have anything for an outboard. If you are in a high crime area, an outboard is relatively easy to steal, on an I/O they'll only get the relatively inexpensive drive. Like everything in life, there's no right answer, everything has it's advantages and disadvantages.
