View Full Version : Typical Engin duration

What is the typical number of hours before a MC Indmar engin needs a rebuild?
Same question for the transmission?

I understand it will depend on care and usage - just looking for approx # of hours.

Looking into buying a used MC, enjoyed all I found on this site, real good stuff.

You're right; the best answer is "it depends." Our '84 S/S has 1250 hours on original engine and transmission; still running pretty strong.

Ballpark 2,000 hours. As you mentioned, that number will vary greatly depending on care and maintenance.

I have a friend with an 88 PS 190 with over 3000 hours on the original motor. It is still running strong.

Thank u all, that was the type of real world info I wanted and it is ball park within my estimates.

Car engin will run for at least 150,000 miles and assuming 60m/hr = 2,500 hours and down grade that because a boat is fast acceleration and often running close to flat out ......so one should expect at least 1/2 = 1,250 hours......and that is a very conservative estimate.

I have 1600 on my 84. Original engine and tranny. Still seems very strong. Haven't checked compression, but is still achieves proper RPMS and doesn't use oil.

I've heard that you should get 3,000 hours, but I've rarely seen a 2,000 hour boat that hasn't been rebuilt or replaced.

A lot depends on the year and your budget. You should be able to easily find an '88 - '91 with 600 - 900 hours. 400 if you look hard.

If you post a specific boat, there's no shortage of opinions on this site. ;)

I've heard to expect at least 1500 before a valve job, then another 1500 trouble free. Diligent maintenance will be better. I have 946 hours on my 87 and it's solid. I bought it new and everything in it is original. It's 21 years old this year, and I'm expecting a lot more years out of it.

studied the history of ProStar 190 by C36, great article and I have a question:

C36 says in his preamble that all the boats he reviews are based on the same hull yet later in the article C36 says the 1995-1997 ProStar 190 was smaller then the 1998-2000; and then about "more freeboard" ..........so are they all the same hull?
Does anyone know what actual design changes were done to the hull? and how do they affect the wake?

I've got 1026 on my '03 X7, runs like they day I got her. I plan on 3000 before any major rebuild.
