How do you remove an outboard jet impeller?
To remove the impeller starts by folding down the 2 flags that keep that big nut from spinning. Then you can get a pair of pliers on that nut and remove it. The nut, flap washer and a bunch of other washers then slide off easily. The impeller then can slide off.
Do outboard jets have water pumps?
The process is fairly simple, but while there are lot of materials online about doing this for prop outboards, I found very little for jet outboards. So here is the basics of how to replace the water pump. The pump is located at top of the lower unit. So the first thing you need to do is remove the lower unit.
What is cavitation on a jet boat?
Cavitation: The jet unit is starved for water, and usually sounds like a rattle or a can of loose bolts in the back of the boat. Most likely a blocked intake grate. If water has gotten into the bearing, it is usually as a result of a flooded bilge at some time on a warm bearing, then water can be sucked in as it cools.
Can you convert an outboard to a jet drive?
Most people don’t know this, but many outboards can be converted to jet propulsion for between $1,700 and $2,700, depending on their size. Boaters who ply skinny or debris-strewn bodies of water on a regular basis are probably better served buying a jet outboard from Yamaha, Honda, Mercury or Evinrude.
How do you remove the impeller from a shaft?
By using a strap wrench, pool owners can gently loosen the impeller and make it easier to unthread. Depending on the model of the pump, the shaft may vary. Some pumps provide a slot on the end of the shaft to secure with a screwdriver. Often times, you can access the slot by removing the motor cap.
Do outboard jet motors have reverse?
-There is no reverse. -You lose about 15% max power compared to a prop. -You should consider a tunnel hull if you go jet.
How do you make a jet boat go faster?
To get more speed out of your boat you need to increase the jets output velocity. This can be done by increasing rpm and maintaining the same nozzle orifice (less efficent), or maintain rpm and orifice but increase the size of the impellor.
