I bought a '95 H18 and I am doing restoration work but can't get the dolphin striker rod out from the end cap castings of the front cross bar. I have removed the respective bults and center post. I think rod is just inserted into end caps but need some help on how to remove the rod from the end caps so I can remove the two inner castings in the front crossbar. Probably seiged but would appreciate any insight. Are the end threads of the rod 1" in length or more? Should I pull dolphin striker away from center of cross bar with pressure while using a penetrating solvent?

The rod is a slip fit in the castings, so corrosion buildup is your issue. Penetrating oil and rotation movement should help free it up.

Thanks Matt, took 3 days with freeze penetrating oil and plenty of banging with nut in to protect thread and ended up having to use car jack between dolphin striker and crossbar to finally get the dolphin striker out from the end caps. The striker has almost 2" through the end cap and is only reachable in the endcap outer side. Corrosion was too bad so bought a used but solid crossbar. Wouldlike to take it apart to put antisiege but have moved on to restoration of other parts. Anchor plates are in back order at Hobie til Sep so that puts me behind on project. Do you know when the anchor plates will start shipping out. I ordered 6 through Beach Cats at PR.

When replacing the dolphin striker in the endcap think about wrapping it in heat shrink tape ( for electrical wire) : it isolates the stainless steel rod from the aluminium. My endcap insides were completely eaten up by the corrosion caused by joining a weak and a strong metal in a seawater environement, I still consider this a design flaw in a otherwise superb boat ( I love my old 18 !)
Also : paint the end ( threaded) part of the rod with epoxy-paint, this end part cannot be shrink-wrapped ( the nut needs the threads) and the paint provides a measure of isolation.
It took me blood, sweat and tears to get the dolphin striker out of the end caps, but worth it : think what could happen when an end cap collapses during sailing....

I bought a new crossbar and dolphin striker assembly about 3 months back. Just waiting for wife to finish with household chores before I tackle the new fit. Then I am after the long distance sea challenges with the H18.

The old one is quite cracked and requires replacing and do not dare rough water sailing.

Cheers
Richard

Marco could you please elaborate on how you used a car jack to get your striker rod out of the corner casting. Ive been beating on mine for hours and it won't budge. Thank you.

The jack is so you don't have to remove the striker rod itself... leave it tensioned. Use the jack to re-seat the post and casting.
