Removing engine while on the hard

Removing the coolant tank/manifold, alternators, transmission and intake manifold is easy. I could remove the head also, as it weights about 80 lbs, but would prefer not to!

In my experience, marina hardstand managers won’t allow engines to be swung out on the boom. I know it’s tempting to try it but the consequences if you fail are unpleasant at best and life threatening at worst. If something goes wrong with the lifting arrangement and the engine gets dropped and terminally damaged, that’s just annoying and expensive BUT if the stands collapse or the keel slides on the blocks and the boat actually topples over while you’re on deck, you’ll be riding it to the ground. If you have other boats nearby the domino effect could cause even more damage, far better to abandon the idea of swinging the Beke out on the boom and get the appropriate machine in to do the hoist.

If your marina has rack storage service for small power boats, thier "Marina Bull" forklift has about 20 foot long forks. No problem reaching inboard with that, even over the stern. And they go like 30 feet high so height's no problem either. I've done it that way too.

About 20 years ago one of the marinas here in Muskegon (the one that had the big fire last week) played boat dominoes when a DIYer pulled one too many jackstands to paint the bottom. Around 12 boats got knocked over. Huge mess. Yeah, don't be that guy. When I pulled my engine there wasn't anybody near me.

Yikes!

We plan to do it when the boat next to us goes in the water. Partly because we can drop it into the bed of the truck.

I'll talk to the marina. They do have a forklift but nothing with big forks. Their travelift has a small crane on it, but I don't think they can get it over our center cockpit.

Could they get to it in the cockpit if you take off the boom and drop the back stay?

Most yards I have been in have a crane that costs about $150 an hour. The whole process could be done in 15 minutes from engine mounts to resting on the ground. No risk to your boat, and huge savings in your time rigging up something you are worried about.

Somethings ARE worth paying for.

The boatyard I'm at now does have a crane on their travel-lift. Once the boat next to me goes in, it might be able to reach.

If they say they can do it, then that is my first options as it's the least risky.

One more point in Jackstands. They are not meant to lift the boat or support it any more than just keeping the boat vertical. Boat is meant to sit on its keel and jackstands support very little weight. If hull is sandwich structure, and you lift the boat by jackstands alone, for instance to paint the bottom of the keel, you could risk de-laminating the hull in area where jackstands are. At the very least make sure you are placing jackstands in area where strong bulkheads are. This may not be possible.
