Boats that are in saltwater mainly have to deal with salt corrosion but other than that theres no real difference. Yes there are some differences between saltwater and freshwater boats.
Saltwater can corrode metal up to 10 times faster than freshwater.
Difference between saltwater and freshwater outboard motors. An outboard motor is a small boat engine that attaches to the rear of the boat. Boaters use them in all boating conditions including in freshwater and saltwater. The design of the motor varies little even when the motor is used in different water conditions.
A motor owner must take great care to prevent corrosion. 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. 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. 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. Outboards in general are preferred for salt water because they can be tilted up out of the water.
The anodes if used would be different depending on if the engine was used in salt or un-salted water. Aluminum or zinc would be for salt and magnesium would be for fresh water. The engines themselves are the same of course.
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. It the motor was bought new and dunked in salt water it was used in salt water.
If a motor was bought new and dunked in fresh water it was a fresh water boat. Mercury did offer a salt water series however that was a larger outboard and a salesmarketing name. In general motors which have a history of use in salt water are generally discounted in value as compared to motors which have been only used in freshwater.
The part often mentioned as changing in a saltwater motor is the tilt tube an area which is subject to corrosion in salt water. You need to watch with fresh water. If its pure freshwater then you can use either the Aluminum or Magnesium Anode with the magnesium beeing the anode of choice.
Now if your in polluted freshwater you only want to use the Aluminum Anode. Never use the magnesium in polluted freshwater or saltwater. FOr saltwater you want the Zinc or the Aluminum anode.
Planing hulls can range from 8-foot long rigid inflatable dinghies to 100-plus-foot motor yachts. These motors are usually controlled with a tiller handle and are nearly always started with a pull-rope like a lawnmower. While most outboard motors are water-cooled some of the smaller portable models are air-cooled.
The only reason is the expense of a salt water motor vs freshwater. If you already have it it will work fine in fresh water. What is the difference between a saltwater outboard motor and a freshwater outboard motor.
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. It is important to know that saltwater can wear out boat components quicker than freshwater use.
In this article we will discuss the differences between freshwater and saltwater boats. We will also discuss common issues and what to be aware of if you do take your freshwater. When it comes to choosing a motor type for saltwater the difficulties that you will encounter are similar for the two motors but these issues are typically easier to deal with on outboard motors.
Saltwater is highly corrosive meaning that the motor will need to be flushed after each use with freshwater. Freshwater is inland water. Saltwater is seawater and it contains a lot more salt.
Boats that are in saltwater mainly have to deal with salt corrosion but other than that theres no real difference. Generally a saltwater boat doesnt have a different hull shape and doesnt use other materials. Click to see full answer.
Its no secret that the lucky Keith Kavajecz spends his winters catching saltwater fish but did you know he uses the SAME motor. In 2020 all outboard motors will function equally well in freshwater or saltwater. Therefore any outboard motor can be used in saltwater.
Therefore any outboard motor can be used in saltwater. Saltwater is detrimental for your outboard motor not in its ability to decrease motor performance but in its insidious capacities for causing metal components to rust and. For those new to the boating game.
Yes there are some differences between saltwater and freshwater boats. In this post well cover these differences so you have a better idea of the boat type for your needs. Saltwater boats are designed to better handle corrosion resistance for obvious reasons.
The main difference between the fresh water and salt water motor is the material they are made of. For saltwater use the motor compartments are made of material that repels corrosion brought by the corrosive properties of the salt water in the ocean.
