Ask Nort how many hours he has AFTER the "upgrade".

Oh snap! :D

I think 150ish hours? Zero in the last two years.

Like t500hps stated, The drives will eventually go. How soon, depends on how rough the water is you boat in. Re-entry is tough on drives, especially one as heavy as the 382.

i am new at this forum stuff, but I see that you have arnesons and I would be curious to know how you like them and if you don't mind what they cost. I am also a Lake Erie boater and keep mine at Castaway Bay Marina, the old Harbour. Do you ever go to the Casino, I 'm usually there several times a summer.

Freshen the the top end while you're at it, replace the head gasket (someone mentioned), and save up for drive upgrades. I have a 2001 and added Whipple 3300s at about 275 hours when freshening the top end. Lots to do......you need gauges so that means a new dash, electronic fuel pumps, and some grinding.

I see the new dash, but where did you put the gps?

In a cupboard in the garage. It always slowed the boat down. :)

Been doing some research on drives and it seems that for reliability the choices are an Imco SCX or the Arneson conversion. Do the Imco's hold up or are the Arnesons the best answer.

The new Imco SCX4 looks interesting to me. I wonder how a surface drive (non Arneson) would do on a 382 or 353..

The Arneson's are probably the best answer if all you are looking for is speed. For me, I would not want something hanging that far off my transom. I'm liable to jump off the back and on to a prop.
