Re: Reliability of mercruiser 7.4 l
Mr. o4fxdwigi,
Thank you for your comments. I got the idea about 4 years because the NADA boat price guide only listed 5.0, 5.7, and 8.2 litre engines with a sidenote that for 1993 thru 1997 model years to use the 5.7 even if the boat had a 7.4 litre. [?] I thought that was strange, but well, OK. Secondly Mercruiser's own site only gave info about 3.0, 4.3, 5.0, 5.7, 8.2 litre engines with no mention of a 7.4 ! Almost like they were embarrassed by it. At that point I'm getting nervous. So I posted the question. Later, after visiting a dozen more sites, I came across the mention that GM had cut back production of the 7.4 and moved the line to a smaller plant to make room for producing the new 6.2 GM engine at the plant where the 7.4 had been made. Then cutting back supply of the 7.4 [454] to the marine industry in favor of shipping most of them to automotive applications. I began to feel better knowing there was a reason Merc reduced the use of the 7.4. Believe me, I know the 454 block has been around a long time and is bulletproof in autos. This 2500 sx I'm buying is absolutely in mint condition cosmetically [can't tell it from new] and I thought why would anyone want to sell it unless there was some underlying expensive mechanical issue. I guess I'm just overly suspicious. This engine will get excellent care under my watch, and thank you for easing my mind. Regards, David.
