Will it be "easy?" No -but much easier than you may expect. Depending on your boat and the access you have, pulling the old engine out could be an hour's job! Once you have it on a stand you can take your time and ask questions along the way. more
Don't be afraid of a truck engine - it doesn't have to be a marine engine. You will be able to transfer your marine externals to the new engine. (There are some things you will need to do - like make sure you have brass core (freeze) plugs, etc, but those things you can take care of as you get to them). There were several differences in 4.3 liter engines however, so to make it easier on yourself, you ought to buy an engine of the same vintage as the one you currently own. more
Check your local Craigslist for S10 / Astro / 1500 chevy vehicles. There are others too. I found my replacement out of a 1992 Chevy Silverado 1500. Since your boat is much newer, it will probably cost a bit more for a replacement to match your current engine. You can also check ebay and www.car-part.com for engines.

I had the exact same problem with my 2007 Silverado 1500 work truck, intermittent grinding trying to shift from 4wd low to drive and vice versa. Also had transmission fail twice in 2 miles while driving to my dealer; engine kept running but my truck slowly rolled to a stop. At first the Chevy dealer told me "no problem found" but I demonstrated the grinding to my advisor; they did a minor repair but trans. was still malfunctioning. I paid $200 on that first minor repair and then their trans. mechanic diagnosed internal transfer case problem and my CARMAX warranty approved replacing it after they'd sent an inspector to the shop to verify the problem. I'm certainly happy that I purchased this CARMAX service contract as the new repair bill of $2,800 will cost me nothing.

Chevrolet owners are advised to seek out repair service at your Chevy factory-authorized dealer. In addition to using genuine Chevrolet parts, dealers have firsthand knowledge of your vehicle, as well as the latest service bulletins and recall notices as issued by the manufacturer.
General Motors announced in August 2018, the creation of the General Motors Collision Repair Network. The network is designed to drive customer safety, satisfaction with strong results for dealers and independent collision repair facilities. Using a directory maintained by GM’s OnStar division, the group will direct GM Vehicle owners to the nearest GM-approved service provider (which may or may not be a part of a dealership) where qualified technicians will follow specific factory-prescribed procedures in making the repair.
In the case of a leased GM vehicle, many car leases including those from GMFinancial will require the use of genuine General Motors original equipment parts when making the car whole again. This is regardless of whether your insurance company will pay for them or not. If your coverage excludes original equipment parts, be prepared to spend out of pocket to fulfill the difference. more
For Chevrolet vehicles with specialized construction elements, such as aluminum panels or carbon fiber, a GM-approved facility may be the only option for getting it repaired properly. here
Auto Repairs Are EXPENSIVE
Although getting your rear main seal replaced is crucial to fixing your car, you can drive with your seal malfunctioning. However, the oil will consistently leak out of your car, and you will need to top up the oil much more often than if the seal had an air-tight fit. If you drive with low oil, you can easily damage the camshaft and the other parts that need oil to act as a lubricant, prevent wear and tear.
After you have cleared room for the transmission and removed the unnecessary parts, you are now getting to the rear main seal. The anatomy of the rear main seal consists of a cylindrical metal piece in the middle of the seal – this is the crankshaft. The smaller piece in the center of the crankshaft is a pilot bearing, included on only rear-wheel-drive manual cars. [links]
