Trojan Boat Forum

on my 76 f25 just above the rudder theres a plate that goes between the rudder and housing does anyone know if its oe or aftermarket between the plate and housing theres a 3/8s gap i have pics of the plate if someone will post and there is no part number on the plate [/img]

Here are the plates.

The plate very well maybe a Trojan only as I don't think its a common part . the stuffing/packing box (housing) looks like a std Buck Algonquin part the packing box looks like the warped part .

I would not worry how the 2 parts fit together as part of the hull goes between them . How it fits to the hull is more important . a 3/8 gap in places would be to much. If it tightens down OK and is slightly uneven thats ok , a good sealant should do the job 5200 or 4200 will work .( my choice is 5200

thats the way it came off the boat just like that the plate was attached to the stuffing box then bolted tothe boat

That seems wrong is there another bronze plate in the boat ?

If not the large plate goes under the boat and the packing box goes inside .

Do you have a photo of the hull by the rudder ?

i will get pic

You're missing part of the rudder port casting... The plate does go directly up against the hull, but the rudder port is missing the three inch long part of it's casting that fits down thru the hull and thru the hole in the plate. You need a new rudder port. Hamilton Marine is one source and you can order online.

If I recall John at Marine Tech correctly, the plate was Trojan's attempt to hydrodynamically extend the length of the hull to improve handling.

jon_e_quest I believe your right about the port missing part of it ( I should have caught it ) and I believe your correct on the purpose . and we both agree plate under the hull port above inside the hull

That's right... rudder port mounts inside the hull. Plate goes on the outside. And kicker should NOT be using the rudder port in these pics for anything but a paper weight!

yes i know the rudder port in pic was an extra that came with the boat i know someone cut it just using it in the photo i know its not any good heres the two pics from under the boat mg][/img]

Kicker, the plate you have is an original equipment item used on all Model 253 F-25's and was designed by Trojan to improve handling. It's shaped to fit up over the protruding end of the rudder port directly against the hull. As prowler suggests, use adhesive sealant when mounting (I prefer 3M's 4200 over 5200 because it's easier to remove the part later should it ever become nessessary).

Run a bead of sufficient size along the plate's hull footprint and around the rudder port and mounting holes. Let completely cure before relaunching.

Before you reinstall is you need to clean that area and inspect it . I see what could be cracked fiberglass

That just is not right , on the out sude chance that port went on the outside there would be a plate on the inside

thers not a plate on inside but i am taking all of it out and putting stuffing box to inside and plate to outside
