To set a shaft and propeller it is advisable to put on a pair of rubber gloves. This is because the propeller blades tend to be sharp and cause deep wounds. Collect the tools to do the job. You may need a screwdriver, a ratchet, waterproof oil, and a lapping compound. If there is an older prop already in position remove the prop by loosening the nut working with pliers or a screwdriver.

Check the prop for just about any damage. Fitting a destroyed prop will limit engine overall performance and cause harm to the whole system. Check the shaft for fishing lines, aquatic plants or any trash that has been sucked in by the rotating prop. Remove all of the debris and clean the shaft with a towel. If the debris is left in the shaft it can damage the engine and will block the shaft and prevent fuel from reaching the propeller. The boat will start guzzling a lot of fuel if the shaft is dirty.

Use water-resistant grease to the shaft especially to the grooved region. If there are no grooves, apply grease to the whole uncovered area of the shaft. The grease will help the shaft fit easily into the shaft hole of the prop.

Examine the thrust washer. The washer should be perfectly round and fit snugly on the prop. The washer should not have gouge marks. When the washer has gouge marks, it should be exchanged for the superior performance of the boat. The cutlass bearing should be tightened for optimum performance. Inspect the washers and spacers behind the prop and remove and replace any broken part.

Seat the propeller on the thrust washer. Fit the shaft on the shaft opening. If the shaft has got a tab washer, you should twist the washer till it is tight. If there is a cotter pin, tighten up by pressing the pin with a screwdriver and tightening it. Check out the alignment of the boat. Leave the boat in the water for 24 hours then check for any alignment or loose component issues. Remove and replace any overlooked damaged parts and re-install the prop if required. This specific test is important to ascertain if the shaft and prop are properly fitted together.

Stick to the motor guide or the manual that comes with the prop for the best outcomes. A number of professionals feel that the prop and shaft need to be set up collectively by lapping for the best results. If lapping is used then a lapping substance needs to be applied to the shaft.
