Any opinions on the LT1? Its in a 98 205, looks nice, and is described as running great, and it has less then 200 hours. I have no expereince with this engine, anything to look out for?

There's another thread from last week that asked the same question. DO search and you'll get your answer.

Personally, I doubt that a boat from '98 has 200 actual running hours. Disconnecting the Hobbs meter will keep it from advancing but the motor's ECM has a record of how long the motor ran, not how long the key was turned ON. Have a marine survey done. Whether you pay for it yourself or split the cost with the seller, you'll know a lot more about the condition than if you did the inspection yourself, unless you have done many thorough surveys yourself. Make sure the survey includes connection to a diagnostic computer, like a Tech 1, with the marine card. I don't mean plug up a scan tool, that isn't adequate and will never show the data that needs to be viewed and analyzed. I would recommend acquiring this data on the water, not on a trailer.

No Issues w/ my '96 in 4 seasons and about 180 hrs of use. About 450 hrs total on the boat now.
Maintenance is easy. No carb, ignition tuning, etc.
RUns well at low or high altitude.

Thanks for the info. I'll definatly have it hooked up to a diagnostic tool, I think there is a MC dealer near there.

My Bro-in-law has the Corvette engine in his '98 190. Runs like a top. He's just now feeling the need to get it tuned up, due only to the age of some components. While skepticism and due diligence is called for when such low hours appear, his boat does have less than 200 hours on it. It's almost never on the big lakes just tooling around, as it spends most of it's time at our little quarry lake a few hours a weekend, splitting duties with mine.
Good luck,
Kevin

We have one in our '94. Works great. We put gas in and ski or wakeboard. FI is the way to go.

Don't use antifreeze to winterize (heard it's bad for the aluminum heards), just drain & fog.

Plus, your motor has the cool corvette platic cover thingys.

I have 500+ hours on my 98 LT-1 with no issues. Runs great. Make sure it has had the valve springs recalled.

What are the details of the valve spring recall?

Not to "one-up", but my ski buddy has 1300+ hrs on his. It's all still stock, never been worked on besides maintenance, and I swear that engine feels like its only getting broken in. Almost seems stronger every year. He's a Mobile1 devotee though and maybe that helps out somehow.

Yea, ditto that. What's up, Capt.?

In the late 90's GM had a bunch of bad valve springs. It effected a lot of boats with GM blocks (at that point I think all boats had GM blocks). The steel used in the springs was bad and the springs would break. It happened to me. First weekend out, broke a spring. MC took care of it, and by rights my boat should never gotten into my hands without them being changed. It was just one of those cases of one getting missed before I got it. Anyway, odds are the springs have already been changed out at this point.

jim -- i have a 98 sportstar that i purchased in 2001 with 188 hrs. 6 years later, i do not have 300 hrs total on the boat. i might add, however, that my circumstances are unique. so, it is possible, but unlikely.

Capt.-
That would SUCK on the first trip out:mad:. Bet you were a bit pissed.... BTW- for those of us who are unaware if ours have been replaced, could you describe the ruckus, sir???? Or will we know when it happens?

My 97 PS 190 w/LT1 has about 600 hrs and it still runs strong.. No problems what so ever....

Funny I remember in 1997 the SN sales rep was trying to tell me the LT1 motor was a bad bad choice. I would regret purchasing it... HA!

My 98 had 160 hours on it when I purchased it last year. I just went over 210 this weekend. My neighbor has a 98 Sammy Duvall with over 1700 hours and it is still running like a top.

When you don't look at something for a while, certain fine details get lost in you memory. Sometimes those fine details are pretty important ones. Stating that the 1998 LT-1 may have had bad valve springs is only partially correct. Someone asked me about this, so I dug up the paperwork and basically (according to my bulletin) it only pertains to the 30th Anniversary edition LT-1 due to the high lift of the cam in these engines. Sorry for any confusion guys. :o

Funny how SN went from Ford to Chevy I think around 2002/2003. What would that salesman say to that!
(for the record, nothing wrong with Ford or Chevy, as long as it's in a MASTERCRAFT!)

I had no issues with my LT-1 in my 1994 prostar. Ran great!

That's because Ford got out of the marine industry around 02-03. Unless I am wrong, all blocks in boats are now GM.

Nope, youre right. PCM's supply of the Ford blocks ran dry in '02. All Chevy from '03 on.

Ill admit that the LT1's in friends boats ('94 and '95 190's) both perform very well. Not sure how it would compare to the Ford GT40 in the same hull, though. Ive lined up against both Ford (310hp) and Chevy (330hp) powered N-boats (on the same hull), and the Ford gave me a better run for my money out of the hole. The Chevy may have had a touch more top end, but it was close.

Actually, Ford got out of the marine industry in about '97 and PCM bought everything they had left. It took that long to sell through everything. Plus, I would imagine they needed some for warranty replacements and development.

JimN,
I have a 98 LT-1 as well - where is the ECM located on the motor so I can have someone with a diagnostic computer with a Marine card plug in to give me some clue on the true hours. Any gotchas that may happen with the marine survey??

JimN

It should be at the rear of the motor. Look for a harness with a black capped plug, dangling.

Gotchas? Look at the plugs for color, evidence of excessive heat, corrosion in the threads and shine a light into the cylinders. Do compression, cylinder leakdown and vacuum tests. Look in the data for overheats, too. They remain in non-volatile memory for 300 key on cycles.

Are you selling it?

JimN,
Thanks for the words. I've had the boat for a couple of seasons now and it has been / run great. Just want to get an idea of the actual hours on it.

Not selling it...too much fun!!
