In-water propeller polish

In-water propeller polish

Big or small we do it all. The electric grinder polish the propeller without damage while removing unwanted fouling and smoothening the surface. We trust the products of Nemo Power Tools.

Propellers and Thrusters are crucial for your vessel operation. Fouling of the propulsion system can dramatically reduce performance. Aloha Diving recommends Propspeed coating for for your propulsion system. It costs more than a conventional anti-fouling but lasts a long time. That means as well you have less maintenance costs.

In-water propeller change

Six reasons you may need to change your propeller or pitch of the prop:

1. Is your boat slow to come onto plane?
2. Does your engine over-rev and the boat seem slow?
3. Did you run over a log, hit a sandbar or a rock?
4. Do you want your boat to be faster?
5. Using too much fuel?
6. You changed the engine

We can take off as well the rudder and shaft while the vessel remains in the water. Custom tools we can manufacture within 24 hours to get the in-water work professionally done. Custom shafts can be manufactured within a couple of days. Call us before you haul out! We are here to find the most economical solution for you.

Aloha Diving Phuket undertakes underwater replacement anodes (u/w replacement anodes) in the submerged parts of the ship such as rudder, propeller and hull. Changing Zinks is often combined with hull cleaning. As a result, the smooth operation of the ship is extended and the costs of keeping the ship away from the dry-dock are reduced significantly. We replace anodes manufactured by Tecnoseal, a leading supplier of sacrificial anodes for cathodic protection in the following markets: leisure boat, shipping & offshore applications..
