Do I need a hydrofoil stabilizer?


cluelessfisherman

Question

I have an Alumacraft Navigator 165 tiller with a 50 Merc. The hole shot is decent considering it is only a 50 horse with an 11 pitch prop. The problem occurs when I try to trim up just a little to get that extra mile or two per hour top speed. I have had it gps clocked at 31 but it doesn't take long before it starts porpoising like crazy and the speed drops again. The only way I can keep it from porpoising is to keep it trimmed all the way down but then I run between 28-29 mph.

I realize that the stabilizer will help with the porpoising, but my question is if it will create enough drag to take the speed down on the top end - I would be defeating the purpose of wanting that extra mph. I also pull tubes with my boat and it struggles getting on plane - the person in the tube usually ends up rocking the tube to help the boat get on plane. I believe the stabilizer would help here as well.

Please advise.

That is pretty much typical when you over trim. I am no pro with the hydrofoil things, I understand that they do cause some drag which would bring down the top end. If you motor spins enough rpm you may be able to jump to the next pitch up on prop to get the added speed.

I have a hydrofoil set that you try out and take off my hands if you like. You have to drill 4 holes on a plate just above the prop on the lower unit (no big deal). I can bring it to Rainy next week. All you need is a drill/drill bit and it can be installed in five minutes.

I have not idea how your boat will respond to it. Seems like every boat is different.

Let me know.

Derek - I'm running at about 5200-5300 rpm's on top.

CD - I will have to take you up on that. There are holes there already - hopefully they match up. Do you have the hardware with them? If not, what do I need?

Thanks.

When you are fully on plane the cavitation plate is not in the water and will have no effect at all. You can mess with engine height a little, or realize this is not a proformance rig and fish on. good luck

Clueless,
I'll find the hydrofoil and bring it with to Rainy. It's packed away somewhere from my move(s) last year.

I have the hardware for it (bolts/screws). All you need to bring is a drill and about a 1/4" drill bit just in case the holes don't match up.

Clueless,
I had a Alumacraft Magnum 165 with a 50 hp Yamaha 4-stroke. I add a hydrofoil to it and it helped the holeshot a bunch without any ill effects on the top end. I would say its well worth the investment.

      Went up Tuesday. After scouting for duck hunting locations I fished for ~ 3 hours. Tried a hump off Crow point that had some fish found with LiveScope but no takers on jig and fathead. Trolled the shore south of Linwood Pt with a Salmo hornet, no takers. Trolled a spinner and minnow outside the weeds off the big point. Had a strike and 2 north (25" and 28") in 20 minutes. It was a fun day to be out on that lake, very calm. The pic is Cody watching a loon near the boat. I thought he was going to jump out a few times. A lot of young of the year loons on the lake.

      Those who are in the real estate style business are constantly on the move and without software it is difficult for them to manage this business. My relative is engaged in mediation between the tenant and the supplier, and he cannot imagine effective work without the necessary program, he has such a program on his phone, he ordered it on some server, but now it does not work correctly, he needs a new one. I looked at the site that you advise, I will give the link to this company to him, let him look...

      I think property management is more about communication than real estate as it requires regular interaction with property owners, tenants and staff. To create a base of loyal customers and ensure future growth in a competitive market, I recommend ordering the development of a mobile application fromhttps://djangostars.com/industries/proptech-real-estate/. Because managing a large real estate company that has been on the market for over 20 years can be a headache if you don't have the right software to manage it.

      Buying and selling, renting residential areas include many long-term labor-intensive processes. It is easy to optimize, speed up these operations - it is enough to order the creation of a mobile application for real estate.

      This is the right decision, because such software will allow her to work less and more conveniently. Therefore, find its own developers. In your city, if it is large, you can find such a team, if not, then on the Internet

      don't know what roulette is? Hi. Roulette as I think is a very cool game. Roulette has been played since the nineteenth century and every self-respecting casino, including online casinos, be sure to have it in their assortment https://aolbroadband.in/ .Games for free, which the guys provide on this site, of course, include the most popular varieties of roulette: American, European and French. The online version of roulette is no different from the well-known one from land-based casinos: it features a green table with marked numbers and betting fields, as well as a wheel with numbered cells on which the ball rotates. On this site you can learn more and even play it

      In addition to to Feichao, you can also consider the DJI Mini SE. This is also an excellent piece. However, always try to read articles and thorough reviews before buying.

      Mini drones like Feichao Mini Drone Quadcopter M9 are good to take footage.

      My grandmother is a very old person, and she has had a real estate company for 20 years now, she has dedicated her whole life to it, so she does not understand much about technology and is looking to modernize her business, she is one of the few real estate companies that They don't have their own application, so I see myself in charge of finding a good software developer for real estate and that type of business. Do you know any professional or company that is dedicated to it?
