Re: data on 102 motors

Were the stator plates used on other (non Seagull) motors ?

Re: thrust and bhp

Just a question ...

Does the thrust change (at WOT) from when the boat is tied to a bollard to when the boat is moving a maximum hull speed ?

Re: Two motors or One?

One plus of putting a Seagull together from a box of parts is that the tiller can now turn almost 90 degrees to the transom - my boat can now spin in her own length .... works well with a 40+, the C100 just cavitates !

Re: Two motors or One?

I suppose it was a bit confusing for a few, but after a Piña Colada (or two) who could tell where anything was going !

Re: Two motors or One?

I was fascinated watching a cruise liner spin (bow and stern thrusters and twin drive pods) in its own length in Milford Sound, all the while showing the forward view on the wide screen.

Re: Proper water jacket cleaning

I did that with a spare Silver Century block, then to a C100 block. The only advantage is that it gives extra access to the water gallery for cleaning.

Re: Proper water jacket cleaning

I suppose if the inside dia. is as large as possible (as it looks like you have done), then there might be some benefit. On the other hand I found the greatest amount of sound comes from the open intake. If you are happy about drilling holes in a block, why not pair the two holes underneath, drill a...

Re: Proper water jacket cleaning

... In my cylinder I will add 15cm pipe which is OK to spray some water in the exhaust....

Re: Proper water jacket cleaning

Ah! I see. What is the length and inside dia. of the 'water spray' pipe ?
I assume Seagull knew what they were doing .... is there a risk of water ingestion through the exhaust port ?
I'm thinking salt water effect on the cylinder.
