Being hauled soon-a few questions

Hi Lacabina and welcome back,

Curious... how were you were deleted? Your membership has been intact since 2004.

If you had problems logging in, let me know and I'll try to help. It could be related to the security settings on your browser.

Best,

A little overdue for that haul, eh. As for pulling and balancing the shafts & props; IMHO if it ain't broke don't fix it. The spin is another story. In neutral it shouldn't spin. Sounds like you're still engaged. The linkage may fix that. The tanks may very well look terrific until they start to leak or clog your motor. The problems will be inside. Your yard should be able to recommend someone local to clean & inspect them. PLEASE don't try that yourself. I'd also be changing belts, hoses and inspecting the intakes for mussels, etc. & make sure the seacocks are working. Of course inspect and repack the shaft logs.

Find a good engine machine shop, have a valve job done, and have them press in hardened valve seats. That's the biggest and first concern when switching from leaded to unleaded.

Just reread your post:

Is that since rebuild or what year are those motors?

why not a diesel enginer?

HI!
I should put some diesel enginers insted more power an diesel is safetier.

A simple statement will answer why this isn't the best answer for this guy or his boat . "The Power to weight ratio"

960hrs in 40 years, you would have to run for 100 years to pay for cheaper running Diesels.

Hi,

FISH- Before you shut down on overspeed- The original poster was asked if that was the original factory frsh to today hours or if they were rebuilds.

He hasn't answered yet so no one except him knows how long it took to run up those hours.

If they have actually gone for 40 yrs untouched and still run strong I would be inclined to leave them alone. If the heads were done up as suggested the improvement to compression may be the death knell of older piston rings.

During my apprenticeship I found that this not an uncommon phenomenon when doing a cylinder overhaul on older gas engines.

Fish & K1W1 are correct that the power to weight ratio won't work out well, and the cost couldn't be justified since diesels would cost more than the boat and would out live it by decades. Two other points to consider: I doubt if the stringer and mounting situation is equipped to handle the different motors without major modifications. Additionally, nobody would ever expect diesels in this boat so he wouldn't recoup $.10 of the investment at resale. The main thing I was thinking when I asked about the age of those motors was do they really need leaded gas? I doubt it if it's been repowered along the way since 1968 which is very possible.

Hi,

NYCAP- It was your question to the original poster that spurred my reply to FISH.

Another thing to be considered is that if these are the original lumps hey have done somewhere around the equivalent of 50,000 Road Miles ( I have read elsewhere that 50 miles is approx equivalent to 1 hour of engine running, although when I did my time the machines use to get their first service at 50 hrs or 1500 hrs) so they should still have a good squirt left in them if they are looked after correctly and not run WOT all the time.

Lacabina asked me to paste this:
427's

With diesel motors you'd be using an addative with each fill up. No big deal. Considering your situation I think I'd just buy the lead addative in bulk and enjoy the boat. Sounds like you've got a winner.
