Both fresh and saltwater models come in a range of thrust powers designed for every sized boat from the smaller vessels only needing a 12v 30lb through. A comparison between fresh and salt water motors shows 2 improvements that the salt water models have and those are related to corrosion protection.
Mercs have seemingly been the king in terms of corrosion protection though I dont know why for sure.
Is there a difference between saltwater and freshwater motors. They cycle the water through the system and flush it out along with the heat from the motor. Theyre ideal for freshwater conditions because freshwater is less likely to corrode the internal mechanism of a motor. But since saltwater can cause rust to form inside a motor then the raw water system wont be ideal.
Saltwater corrodes metal 10 times faster compared to freshwater so the parts of the engine are corrosion-resistant. It requires very careful maintenance to keep the motor running in good condition. Due to the properties of saltwater the motor contains more stainless parts than a.
Is there a difference between freshwater and saltwater outboard motors. In short freshwater poses very few problems to most vessels while saltwater requires careful maintenance. Saltwater can corrode metal up to 10 times faster than freshwater.
You can use an outboard motor with raw water systems in saltwater or freshwater. Corrosion The main disadvantage of raw water cooling systems is using the system in saltwater. The salt will corrode metals and shorten the life of the outboard motor.
There is actually a difference freshwater motors often use aluminium for many parts a saltwater motor will often use stainless steel in its place making them much more expensive obviously Plus many freshwater motors lack anodes entirely or are quite small these will disappear very. I can personally say the steering components on a minn kota terrova are different between the fresh and salt water motors. After about a year of saltwater use the freshwater ones can have the steering stick a bit.
I have a freshwater ulterra on my boat and expect a year or so out of it. I made some phone calls to motorguide to ask them the main difference between the fresh vs saltwater trolling motors and I was surprised to hear that the only difference was the saltwater motors have a zinc chromate coating on the lower unit which makes it fight against corrosion. I think there is less difference today in saltwater series motors and freshwater motors than there was in the 80s when Yamaha experienced catastrophic problems in saltwater.
Mercs have seemingly been the king in terms of corrosion protection though I dont know why for sure. How to tell if outboard is salt or freshwater Saltwater series motors just had a few sacrificial anodes here and there. Had nothing to do with the motor itself per se.
Bottom of the mounting bracket the trim tab and a piece that clamps through the lower were made of zinc and should be unpainted for them to work. The main difference between saltwater and freshwater is the salinity content. Both contain salt or sodium chloride but freshwater contains only small amounts of salt.
The EarthÛªs oceans and seas are saltwater ecosystems while lakes rivers streams marshes and ponds are freshwater ecosystems. SeawaterÛªs viscosity or internal. More recently Mercury started marketing a Saltwater version of its larger motors.
They claim greater use of stainless steel than the non saltwater models. I have never analysed the difference. Most outboards from the 70s have anodes so that is not the difference between saltwater and non saltwater models.
Salt water is incredibly harder on motors than freshwater. If you can find a saltwater boat that has been only used in freshwater youll be better off. That said todays outboards are are unbelievably reliable.
Just so what does salt water do to boats. However corrosion like boat cancer occurs quickly and can be quite devastating. Yes there is a huge difference in a saltwater trolling motor and a freshwater trolling motor.
Pretty sure the only reason you see a black trolling motor on those boats is for looks. It would look bad to have a blacked out boat with a white trolling motor. Save Reply bobber Registered Joined May 11 2005 2291 Posts 6 Jan 14 2011.
Difference is epoxy coated board zinc anodes to protect against corrosion and stainless hardware. Ive always bought the salt water models but I have friends that go with the fresh water models and are happy with how they stand up in salt. In freshwater lakes and rivers your IO sucks in raw freshwater it cools off the engine and gets spit back out.
This is fine with fresh water but salt water getting run through an engine can be damaging to an engine if it is not thoroughly flushed with fresh water after every use. Im debunking any and all myths about the differences between the API test kits. I do a couple simple tests to let you know what the differences between the.
I talked to 2 different repairs shops and they tell me the only difference between the new freshwater motors and the Riptides is the corrosion proof paint used on the Riptides. The new Traxxis motors have composite shafts so corrosion there is not an issue. Thats why its not advised to take your freshwater motor into saltwater but it is okay to use your saltwater in fresh.
Here are some of the main differences and frequently aswer questions. Are saltwater trolling motors more powerful. Both fresh and saltwater models come in a range of thrust powers designed for every sized boat from the smaller vessels only needing a 12v 30lb through.
These cathodic protection systems run electrical currents through the boat engine to prevent galvanic corrosion. Freshwater boats tend to have hull shapes and fins better designed to be near flat shores and handle flat waves. Saltwater boats have designs better suited for rougher conditions.
A comparison between fresh and salt water motors shows 2 improvements that the salt water models have and those are related to corrosion protection. The salt water motors have a sacrificial anode made of zinc that will corrode protecting the other. What is the Difference Between Freshwater and Saltwater Motors.
Fresh Water Trolling Motor There are some important differences one should think of before selecting a fishing motor. Freshwater has a 1 dissolved salt content. However this salt density is higher.
Its no secret that the lucky Keith Kavajecz spends his winters catching saltwater fish but did you know he uses the SAME motor. However there is increased risk for corrosion on metal components. Apply a thin coat of oil or grease to exposed metal and rinse the trolling motor with freshwater after using it in saltwater.
Is there a difference between freshwater and saltwater trolling motors. The main difference between the fresh water and salt water motor is the material.
