454 Advance
« on: November 19, 2020, 08:31:07 PM »
New member here, working on reviving a Ď87 Advance left for dead. Bought the boat engine-less (originally had a PCM 350) and figured that a spare PCM 454 might drop in without too much fanfare. I saw the quote below from Ron in this thread.

We did MFG. show ski specific boats based on our regular production models, we beefed up the pylon mount and installed a taller pylon, some Advance were built with 454's as well.

Curious if anyone has or has seen such a beast, or if anyone involved with their design or build could enlighten me on a few things. The initial install hit a small snag when the quick drain fitting on the bottom of the pan hit the hull... will remove it but boy, itíll still be tight if I can get the engine low enough to align it. It appears that the floor and motorbox may need to be notched for the rwp as well... maybe indmars were used originally but the crank mounted pump wouldíve been tight on the box (or pylon) too.  Thirdly, the motorbox looks like itíll need to be raised an inch or so, it fits LxW (other than the rwp) but is sitting up on the exhaust manifolds. Curious what mods (if any) were required to fit the big block in the boat... might shorten our learning curve a little. Thanks!

A few pics. Engine is currently cranked up on the mounts to keep from hitting the hull. Rwp is removed because it would have hit the floor. Pic at bottom shows a pic including the pump for reference. We are reusing the 10-17 for now to simplify shaft length and coupler size.

I apologize for the image size, not sure how to correct (Iím on my phone and using Imgur to host). Also donít see an edit feature...
