Re: 36'' Maiami Crash boat used for camera boat.

I use SAE 90 mixed with some additives to help it stick which seems to work ok Martin. I can't get grease into the shafts through the oiler tubes (Maiami and MTB) as I have to remove the rudders to take the shafts out which is a pain ( I could try and inject grease but it would take forever to get through and would probably just come out the top end anyhow). Grease is fine for plain bearing shafts but with the new shafts I have ( for the ST) with double seal each end, they will need filling with oil so it seeps through the bearings, (grease will just sit on the outside and not lubricate) Also, unless you use marine grade waterproof grease/oil with anti corrosion additives the shafts (and bearings) can still rust unless they are stainless or brass. I used to run my nitro boats in the salt water and even though I greased the shafts (steel) thoroughly every time, if I left them for a few months they would be quite rusty when I checked them (using std GP grease, -I always thought grease was grease). I've found it's a good idea to remove the shafts periodically to make sure they aren't 'growing' in the middle as if any rust gets too bad you may not get the shafts out.

40'' Seaplane Tender, new build D

Motors I'll be trying in the ST are either the 'Gool' (black motor) 540 (replaceable and brushes and adjustable timing) or the Feilun boat spare 540 motor complete with mount and cooling. Also bought 4x stainless 250mm driveshafts with ( $8 NZ on a big discount on Banggood) remains to be seen how good the bearings are. Will be running twin motors through twin car ESCs.
