Title: Need advice on diverter for 12JE
Post by: Knightnight on March 12, 2021, 06:47:28 AM: I want to install trim kit for my 12JE. I have been looking at the place diverters but all seem to have cables above the water line. This is a rec boat, not a race boat.18ft Jack Keaton.

1. Is there a diverter I can install that has cables below the water line, in addition somehow below my swim platform/jet cover? My boat has a swim platform cover that sites directly over top of the pump. I am not sure if any diverter would be compatible. You can see from the link my steering and reverse cable mounts are mounted low on the bottom rear transom. I would like to run the hydraulic trim control lines on the left rear bottom transom. Could I somehow use the existing lower right rear reverse cable hole with place diverters?

2. Also do the diverters include a rudder or can I keep the one I have?

It has a swim platform cover like this:

It may also be possible to utilize some of your brackets.

The 4 holes visible in the straight on picture is where the existing swimplatform/pump covers mounts.

Steering and reverse cable are on the bottom right rear (two holes directly on top of each over)

For clearance underneath between the swim platform and the pump there isn't much. You can see the exposed steel color right on top of the end of the pump, that is where a block of wood sits and the swim platform rests on top of that. So maybe 3 inches or so between nozzle exit and top of swim platform. Picture of swim platform design in in my original post, 2nd link.

If you go with a Place Diverter you will need their rudder if you think you need one. My boat had their large rudder (see pic)

Post by: Knightnight on March 18, 2021, 07:02:59 AM: Gotcha thank you. I ordered a place diverter fine tune kit for my pump. I will tackle a re-boarding ladder or swim platform after I get it installed. Might just do small aluminum swim platform to the side of the pump. Maybe one all the way across but I don't want to interfere with the clean out port of course.

Post by: Jered503 on March 19, 2021, 09:57:13 PM: If you’re talking about my old boat pics, I’m pretty sure it was a JE, it only had the two control cables coming through the hull, JF has 3 the extra for the stock electric trim. I was told it was a JE when I purchased it, but yeah mostly the same pump either way
