Im looking for a 90HP 1998 Mercury Power Trim Tilt Cylinder rebuild kit - PN: 813432A3
Hi guys,
I have been without a boat for a while and have just got another one, with a 1998 90 HP 2 stroke mercury engine, and after the first trial run, noticed fluid leaking out of the top seal on the Trim Tilt cylinder.
I have been searching for this part for a few days now online, but seems there are only a few in the states, and the postage is ridiculous..
Does anyone know where I can get this kit, as suppliers are telling me it is superceeded with a full shock rod Kit at over $500...?
I could settle for just the front end seals, as it seems to only leak there, and i have stripped the cylinder, and there is no damage to the O rings or piston bore inside..
One more thing - does anyone know how to remove the bottom trim assembly pin if it is ceased onto the shaft, as the cotter is removed and the shaft only moves slightly left, until the piston bottom mount touches the left bracket, and the piston is ceased to the shaft on the bottom bush? I have ordered a bearing puller to try and put some pressure on the shaft to free up the bush, and dose it with inox every evening..?
I started by removing the bottom section to replace and check the waterpump, and have got the kit for this, and have noticed that there is a rubber seal in the kit that was not on the waterpump when I removed it, and looked at youtube to see if this needs to be fitted on the main shaft, and it is shown on all youtube videos of this model, but have the manual on the boat and this top waterpump seal, on the shaft above the waterpump casing, is not shown in the manual? to fit or not to fit?
Anyone have experience in this area? I think it was left off by mistake by the previous mechanic, as the reason I pulled the bottom end, was that too much water was flowing out of the casing joint, IMHO, and the tell tale was not blowing out faster on increased revs, so deduced water pump issue.. it would make sense that the water pressure was escaping through the casing, not getting forced through the motor, if this seal was left out at the last repair... there are so many models and info on these engines, it is hard to work out what information is for what engine.
Would appreciate any help or advice regarding this.
Cheers

If possible, find and
If possible, find and download a service manual from the internet.
It should contain the size and diameter of all the seals within the trim unit (pretty sure mine does), then take that information to a place in welshpool called Transeals and they should be able to sort you out.

Quicksilver parts..
..seems no one in the states will ship genuine parts over to Australia, and they are not available here..? The new part to replace this is $380, and is the piston ram, with all seals fitted and the top of the cylinder.. available from Midway Marine in Rocko..
Alternative is to search ebay, and get a recon or second hand system complete for around $450 to $800...
Good luck..
