Got my prop wrench (boating post)
I just got my brand new Yamaha prop wrench from an eBayer at a nice
discount. It's time for the painful (expensive) search for the perfect prop. I know I need to drop the pitch by at least two inches. A cup may be in order to improve the hole shot. The stock aluminum prop doesn't "bite" quick enough and lacks in the top end by 750 rpm's. The variables are endless - diameter, pitch, cup, venting, etc. so this time I'm trying something new. I have a good idea of what the diameter and pitch should be. I'll get a SS prop in that size and let the prop shop tweak it for me. The one thing I know for sure is the F90 is best suited for a three-blade prop rather than a four. Once that is settled, I'm going to look further into the value of a narrow jack plate. So far it looks like the hydraulic plates aren't much more $$ than a manual. |

Casady My admittedly limited experience with Yamaha taught me that the company is pretty damned good matching up engines, props and boats, and that a good dealer is also a valuable resource in prop selection. When I took delivery of my 2008 model boat, the boat factory had just changed the prop it spec'd for the boat and engine combo, upon a suggestion from Yamaha. The factory sent me copies of performance print-outs for several props. I was able to almost exactly duplicate the performance on the factory print-out. Almost every outboard boat I considered has performance sheets available from the engine manufacturer, and those sheets specify props. |

They give you one in the middle of the range of props that are individually ideal for one of the varying conditions. My sprint car has a quick change rear axle. You can change the gear ratio in a couple of minutes. There are three brands around, and they all have a magnesium case. Stuff is brittle, but there are no impact loads.

Variable pitch props and adjustable pitch props are two different things.- Hide quoted text - - Show quoted text - Um, and adjustable pitch prop IS variable. |

They have variable pitch props for ships and planes. Variable pitch props and adjustable pitch props are two different things. What does that have to do with anything? You ever see a stern drive trailer boat? You can change props in five minutes. It's only trouble when they have been on the motor for forty years, like the neighbors at the lake. The guy to the east has a pull start 100 hp Merc. He's big, a auto mechanic, and he pulls it easy. One of those inline six "tower of power" motors. They ones to the West has a plywood homebuilt with a 35 hp Johnston, that dates to when that was the biggest motor. Merc came out with a forty and the hp race was on. The auto makers were having a hp race at that time. The fifties when everything had to be bigger and better. I remember when about one boat in fifty had a battery. Three inboards, one of which was the cop, on the biggest lake in Iowa. Most motors were 5 1/2, 6, or 7 1/2. I remember when all the outboards were too small to pull a skier well. The biggest was a 25, and Kirk weighed 200. All the fifties and sixties boats and motors are still around. Motors don't wear out 14 weekends a year. You can fish all day every day and run the motor less than 3 hours a week. I may put two good sized trolling motors on my boat, with two tillers and a tie bar like sailing scows, and never run the engine at all. 5 mph is a good speed for a cocktail cruise. Charge a couple of golf cart batteries at the dock. They make a 2 hp electric outboard, 48 volt, for three grand. Electric outboards start a 135 bucks. Must be something suitable. One hp is about 60 amps at 12 volts. Adjustable is passe for planes. Quite a few ships and most planes have props not only variable, but governed to a constant RPM On an trailered outboard or sterndrive changing pitch with a wrench in a couple of minutes is all you need. That's all it takes to change a prop. Maybe ten if you have help. Someone came out with a two speed gearbox for inboards. Have your holeshot and top end both. Casady |

I saw one at the show however, the sides looked like the washboard my mom did laundry with when I was a kid and there was a hole in the ass end you could drive a Volkswagen through.. Oh yeah, they put a little plastic board across the back at the same height as the transom.. I checked out their website. Many of their boats have the engines on brackets, and the transom is as high as the sides. I like the ones with a pilothouse, which run 3 to 7 feet long. You can get a flush toilet on the 26 footer. I think one or more of their boats would make an OK coastal cruiser. Are the ripples that bad? Casady I've owned two new parkers. No ripples. JustHate is just being his usual asshole-ish self. My first parker was a 25-footer with a flush toilet in the forward part of the pilothouse. The parkers are a step down from gradys in finish, but I think they are stronger. |

The guy to the east has a pull start 100 hp Merc. He's big, a auto mechanic, and he pulls it easy. One of those inline six "tower of power" motors. They ones to the West has a plywood homebuilt with a 35 hp Johnston, that dates to when that was the biggest motor. Merc came out with a forty and the hp race was on. The auto makers were having a hp race at that time. The fifties when everything had to be bigger and better. I remember when about one boat in fifty had a battery. Three inboards, one of which was the cop, on the biggest lake in Iowa. Most motors were 5 1/2, 6, or 7 1/2. I remember when all the outboards were too small to pull a skier well. The biggest was a 25, and Kirk weighed 200. All the fifties and sixties boats and motors are still around. Motors don't wear out 14 weekends a year. You can fish all day every day and run the motor less than 3 hours a week. I may put two good sized trolling motors on my boat, with two tillers and a tie bar like sailing scows, and never run the engine at all. 5 mph is a good speed for a cocktail cruise. Charge a couple of golf cart batteries at the dock. They make a 2 hp electric outboard, 48 volt, for three grand. Electric outboards start a 135 bucks. Must be something suitable. One hp is about 60 amps at 12 volts. Adjustable is passe for planes. Quite a few ships and most planes have props not only variable, but governed to a constant RPM On an trailered outboard or sterndrive changing pitch with a wrench in a couple of minutes is all you need. That's all it takes to change a prop. Maybe ten if you have help. Someone came out with a two speed gearbox for inboards. Have your holeshot and top end both. Casady What does THAT have to do with anything? Al I did was point out that when talking about props, "variable" does not mean "adjustable". Many people don't seem to understand that. |

You do realized that all the props in question are constant speed, and are so called. If they are reversable they are occasionally called that, in contexts where it matters. Your technical term is used by nobody who actually uses one. Maybe you are confused. Casady Well you are either nuts or wrong. I'm guessing its variable. |

Casady Having ridden with friends on both Gradys and Parkers, there is no way I'd ever say that Parkers were 'stronger' than Gradys. They are sold in the same showroom in Deale, MD, and there is no comparison between the two with regard to fit and finish.
