​Frequently Asked Questions & Other Information
Stainless Or Aluminum?​
Stainless steel propeller versus an aluminum propeller is a common question our boaters ask.  Of course, the first difference is price.  An aluminum propeller is significantly less expensive than a stainless steel propeller.  Performance is another difference.  Stainless Steel will last longer than aluminum.  Aluminum propellers can lose their pitch and rake after a while and this will change the way your engine performs.  Stainless steel will hold its shape longer which will allow your engine to perform at its peak longer.
                    **But, what if I hit something? - Some people worry that if they hit something with a stainless steel propeller, it will tear up their lower unit.  This can happen with either stainless steel or aluminum.  If you hit something hard enough, it doesn't matter which prop is on your boat.

Should I go with a 3 blade or 4 blade prop?
For the majority of boats on Lake of the Ozarks that are just leisurely cruising, a 3 blade will do just fine.  For boaters that require more lower end and mid-range (for example: boaters that want to pull skiers and tubers), a four blade prop will give them the boost they need.  In most cases with a four blade prop, you will have to sacrifice a few mph on the top end.

For propeller terminology, Michigan Wheel has a wonderful list on their website.  Check it out.

Let's Talk About Props

by George & Dorothy Peter on 01/25/18

Whether you have a little boat with a trolling motor or a seventy-five-foot yacht, you won’t get anywhere without a propeller. There are several factors that go in to determining the appropriate propeller for your boat. When you call us at Cool Breeze Marine – The Prop Specialists, we will ask you many questions about your boat and its performance. The basics are the make and model of your boat, length, engine size and year. What kind of prop do you have on your boat now? How many people are on your boat on average? Then we’ll move on to what you want your boat to do: better hole shot, mid-range or top end. The biggest component in determining the best propeller choice for you is what your RPM’s are at wide open throttle. The boat manufacturers have guidelines for what your RPM’s should be to get the best performance out of your boat. If you’re not reaching the correct RPM’s, then you might need to change your prop. One pitch up or one pitch down can change your RPM’s by 200 - 250. Running the wrong propeller can and will shorten the life of your engine.

The number of blades your prop has is also important. A three-blade versus a four-blade is something to consider. Typically, a three-blade is faster on top end and creates more bow lift. A four-blade is better for your hole shot and for keeping your boat on plane at lower speeds. If the maintenance of your boat is up to par, then the only thing that could be holding you back is whether you have the correct prop.

Do you have a spare prop? If you are out on the lake and the prop you are using becomes damaged, what will you do? Having a spare prop could save the day, the weekend or your vacation. Consider the props on your boat as the tires. You have a spare tire in your car I’m sure, why not have one for your boat? Don’t get stuck out in the middle of the lake waiting for someone to pull you to shore. Change the “flat tire” and continue with your fun day on the lake. At Cool Breeze Marine – The Prop Specialists, we can repair your damaged prop and sell you a spare. Sometimes the prop isn’t damaged, the hub could have spun. We can re-hub the prop for you and get you on your way in 24 hours for rubber hubs or in minutes with the new hub insert kits.

Many damaged propellers can be repaired. When you bring us your damaged props, please make sure you bring them all. If your boat runs more than one prop (dual props, left and right, etc.) bring them all in because, even though the others may not look damaged, they could become unbalance due to the impact that the damaged prop received. We can check and balance them for you. When you take your car in to have the tires balanced, they don’t just balance one tire, do they? Look at your boat as your car for the water.

Cool Breeze Marine – The Prop Specialists has been a family run business at Lake of the Ozarks for over 25 years. We specialize in propeller repair, modification and hub replacement. We provide propeller service to several marinas and boat owners on the lake and we stock more new, used and refurbished propellers than anyone at the lake. If we don’t have the prop you need, we can order it for you and have it the next day. We also enjoy all the stories that go along with the reason your propeller is damaged. Stop by and share your story with us and we’ll get you back on the water, so you can enjoy your time at the Lake of the Ozarks!

The Spare Prop Saga

by George & Dorothy Peter on 10/03/17

Over the past 25 years we have had several conversations with our boaters.  The one that never gets old is the "Spare Prop" suggestion.  We believe every boater should have spare props for their boat.

Props are like tires.  Imagine going on a road trip.  You pack your clothes, some food.  Check your oil and such.  Wouldn't you also check your spare tire.  What if you get a flat and you are in the middle of nowhere.  That spare tire and the proper tools to change it can save your road trip.

A spare prop is the same.  If you are our out in the middle of the lake and you hit a log and throw a blade, your boating trip and vacation is pretty much over.  You can try to idle all the way to shore, hook your boat up to the trailer and bring us your damaged prop.  Or you can put on your spare prop and enjoy the rest of your day.  Most props can be replaced right in the water (just don't drop anything in the lake).  Of course it is always safer to bring the boat ashore and replace the prop.  When your boating trip is over, stop by the shop with the damaged prop and we'll get in rotation for repair.

Having a spare prop(s) and hardware is the smarter way to go for any boater.  It's convenient, time saving and helps prevent ruined vacations on the lake.

Swing by the shop today and let us get you some extra wheels for your boat.
