Can I put a bigger motor on my boat than its rated for?
Can I use a bigger motor on my boat than what it’s rated for? It is not a violation of Coast Guard regulations to install or use an engine larger than specified on the capacity label, but there may be state regulations prohibiting it, and restrictions from your own insurance company regarding this.
Can you exceed the HP rating on a boat?
The maximum horsepower capacity marked on a boat must not exceed the horsepower capacity determined by the computation method discussed in para- graph (a) of this section, or for certain qualifying boats, the performance test method discussed in paragraph (b) of this section.
Can you upgrade outboard motors?
Modifying Your Outboard Engine Can Lessen Reliability Lawrence recommends: “ Do not modify your engines. Run them the way Mercury makes them. Every time you modify it for 2 or 3 mph, you’ll lose reliability.” And note that any modifications will void the warranty.
How much horsepower can I put on my boat?
The rule of thumb is based on weight alone, and says you should have between 40 and 25 pounds of weight for each horsepower. For example, a 5,000-pound boat could have an engine with between 125 and 200 horsepower.
How big of a motor can I put on my boat?
The rule of thumb guidelines based on weight alone would be between 40 and 25 pounds of weight per 1 hp. In other words a 5,000 lb boat fully loaded could have a 125 to 200 hp engine. The wide range, based on weight alone, is due to the variety in design and handling characteristics of a given boat.
Can I over power my boat?
Either overloading or overpowering your boat is extremely dangerous. Putting an over-sized engine on your boat will cause your boat to sit too low in the stern, and that will make it much more susceptible to being swamped by its own wake or that of a passing boat.
What happens if boat motor is too high?
If it’s too high, the propeller tends to ventilate, losing its bite on the water and blowing out while turning and in steep seas. “If the prop consistently ventilates when heading down a steep wave, the outboard is probably set too high,” says Dean Corbisier, advertising and public relations manager for Suzuki Marine.
How fast should my boat go?
The average cruising sailboat, such as a celebrated Island Packet 420, will sail along at an average speed of between 8 and 12 MPH under most decent circumstances. The world speed record of a sailboat is a bit faster than that, at just over 75 MPH.
Are old boat motors worth anything?
What is it worth? Outboard motors, similar to wooden boats, are valued by the simple laws of supply and demand. Yet, some fairly common models like Mercury kg-7 “Super 10” and Johnson 5 hp green TD models are fairly pricey in restored condition. Horsepower alone is not a good pricing guide.
Is it worth repowering an old boat?
“Repowering, especially with the cost of engines today, is a significant investment which probably won’t add much to the value of the boat.” “Depending on the size of the motor, you could be spending $10,000 to $25,000 per motor. And if you are putting it on an old boat, it’s not going to increase the value that much.
Is it bad to run an outboard engine at full throttle?
Does this mean an engine should never run at wide-open throttle (WOT)? Absolutely not. Modern engines are designed to handle WOT. Also, during break-in going to WOT, as prescribed by the owner’s manual, is necessary to properly seat the pistons’ rings.
Will a 4 blade prop make my boat faster?
A 3 blade propeller usually offers top speed performance while a 4 blade propeller provides maximum thrust and smooth cruising operation. Four blades have some features of their own, though. They often provide more lift at the stern which will help accelerate the hull, especially if it is stern heavy.
How fast should a 50 hp outboard motor go?
With the new Honda 50 hp four stroke I find it will plane at about 17 or 18 mph. Top speed is 30 mph.
Will a different prop increase speed?
Change Your Propeller If you are running an aluminum prop, changing to even a basic stainless steel prop will usually improve top speed. Because stainless steel is stronger than aluminum, the blades on a stainless prop can be thinner, which reduces drag in the water.
