I See Most People Try To Get Rid Of Boats Over 1000 Hours...i Have A 2005 Chevy Silverado With 4500 Hours That Runs Great. Absolutely No Problems What So Ever.

My Question Is: My Boat Has 781 Hours On It And Its A 1991. As Compared To My Truck Engine With 4500 Hours On It. Why Would I Not Expect To Get That Many On My Boat?

how do u figure 4,500 hours?

I think there a few school of thoughts on this, but just take this as a grain of salt.

I usually ride at 22mph ... and putt around mostly when not riding. So lets say my average speed is 20mph... my boat has 1,000 hours on it, which makes it 20,000 miles. Nothing right?

Then theres the whole single gear issue, the motor is sitting at 3,000 - 3,500 rpm while doing this average speed while our cars can upshift and rev lower.

Then there is the elements of being on the water (assuming your boat is in the water or on a lift)...

I like my theory of 1,000 hours = 20,000 miles though =D

My Truck Has An Hour Gauge On It. It Shows Engine Hours Since The Truck Was New, Mileage And Odometer

I would think mainly due to the high torque and high RPM's that your boat is running. There are very few times that a ski/wakeboard boat are being run at say "highway speeds" or 1800-2000 RPM's. Not to mention the constant start and stop that a boat goes through.

Or Another Friend Of Mine Said....you Change The Oil In Your Truck Every 3500 Miles Right? Well You Change The Oil In The Boat Every 50 Hours.

781 Hours On My Boat Divided By 50 Is =15.62 Rounded Off To 16. 16 X 3500 Miles = 56000 Miles On My Boat Engine. On A V-8 Engine, Thats Nothing.

Is That Another Way To Look At It? Ive Heard A Different Opinion From Everyone I Talk To. Whos Right?

dont think the oil change idea has much validity, but what do i know...

Putting lots of hours on an engine (vehicle or boat) doesn't bother me as long as I am the one doing the maintenance during that time. Buying something with lots of hours on it, not knowing the maintenance history, now that bothers me.

740 hours on a twenty year old boat would probably be considered below average use. Indmar engines are often said to go 2,000 before rebuild, but that's not a magic number. If you maintain it, you can get much more out of it than that. 740 is just broken in.

I just bought a 2002 boat with ~1000 hours and I think I'm happy with it. My logic being that because the guy was using it, so he took care of it. I did ask a bunch of folks about the risks of 1000 hour boats, guys I know that ski a bunch told me not to think twice about the hours alone.

I've always thought 1 hour is equivalent to 100 miles.Therefore,50 hours is about 5000 miles.The starts are tougher on the motor than a car,but remember that our boats do alot of idling.If you are on the slalom course for 10 minutes,the ride including the starts and stops are only about 30 seconds a pass,so thats more than half of the time idling.

I beleive alot depends on how well you take care of it my 2007 X2 just turned 400hrs. So I avereage about 125 hrs a seanon, this ones not over until october for me. But I take care of everything. I firmly believe interior condition will give you a really good idea on how the rest of the boat is taken care of. These engines are mostly just 350 chevys. SO if it blows up I am pretty sure a vortec longblock can be had for under $2000. The rest of the parts have very low failure rate. Get back to me in 10 years and I'll post how she's holding up sould have about 1500 hrs on her by then.

Are hours accumulated on a boat when idling? Or does the transmission need to be engaged?

I ask because esseintally that is how it works on a vehicle with wheels, miles don't accumulate until you are rolling.

hours go up when the engine is running.

Which is why adding a 2nd battery is a great idea. We hang on the boat a lot, and if i had to run the motor for those hours it would add up quick!

the hour meter goes up when the key is on, hours tracked on the ECM are when the motor is running

It is simply because, A boat engine is worked harder. They are frequently under heavy load, and run at higher average RPMs than a Car/Truck..... The damp environment that they are in, all of the time, doesnt help either.

I have a 1993 Prostar 205, I just turned over 1200 hrs on it yesterday. I bought the baot brand new, and I have never changed the trans fluid. The engine gets an oil change and fuel separator every year and an impeller every 2 years. It runs as well as it did when it was new.

run it till blows. replace the rings,bearings Any other hard parts that are close to failure; slap it back together. Open beer and enjoy

Old news but I am proud of her...2759hrs on a stock longblock minus timing chain when water pump was changed out. No puffs of smoke and plenty of power gotta love Ford Windsors.

1478 on my 89 and it runs like a sewing machine! Proper care is the key.

The hours stack up as long as the engine runs when it has fuel injection (recorded by the to ECM), but the older boats had an hour meter that only needed the key be in the ON position.

on our 83 SS we have about 1300 hours and recently had engine apart due to water in oil( i believe it was for the fact that the exhaust flap fell off the exhaust hole under swim platform anyhow had to engine apart and was doing my measurements and with about 1150 hours on it then there was like slim slim wear anywhere on the engine so hours doesnt bother me a bit..i also work in a shop and see cars come in all the time with over 300,000 miles and they run great.. I believe maintence and proper service will give you a long lasting engine....also had transmission apart due to a gasket leaking and there was no wear on that also...the ole 351w is still pulling the skiiers our the water just fine and turning lots of heads at the same time!!
