Engine work needed

[ftu209]

My mechanic told me my mercury horizon 6.2 is in need of work on the engine block and heads I am considering using Jasper engine rebuilders to redo my block does anyone have any experience with them. The motor needs the block and heads gone over and redone. They said the turn around on my block would be 6-8 weeks from pickup, my concern is that they would be on time with this time frame.

I have been around boats my entire life and grew up in the boatyard/boat building business. I have learned this lesson one too many times, no rebuilds, buy new. Unfortunately for me, I was not a good "learner," and it took more than a few lessons, to learn to buy new.

I understand the difference in cost between repair/rebuild and new, and also understand that a new engine out of the factory was put together with precise machinery and technology that cannot be matched by a human.

The "tightwad" I am would never-ever again take an engine completely apart and think everything will be ok, IT AIN'T GONNA HAPPEN.

I have rebuilt pumps, alternators, starters, engines, stuffing boxes, you name it, etc., and finally learned to buy new when something needs to be "machined and torqued" for repair.

My most recent episode was a PCM transmission cooler failure, then a new cooler, dismantle and clean the trans, put back together, ran without flaw for 30 minutes and then, well you know. Yesterday I drove to Chapin, SC, to get a new trans, now the engine has to come out again. Maybe, I did not learn.

Yes, in the past I needed to repair because I did not have the money for new but in the long run, new is cheaper. Whew, do ya' think I learned; I'm wondering if I have, and will probably wonder to my grave?

I still possess a tad bit of levity.

Thanks for your input

Buy a new long block and bolt on your good parts to complete it.

I'll disagree under certain circumstances. I'll take quality rebuilt American made part over a new Chinese part everyday,we have become a throw away society. The big difference I see here with many is that your boat is a tool. If there was another way to get you where you need to be you would do it. Now out of curiosity pilarboat why did you put another PCM trans in, couldn't you have gone with a new Velvet drive? What is the ratio of the 80?

The ratio for the PCM 80 is 1:1, same as the old one (series 40.) I don't have an answer for why not Velvet drive. You are right about Chinese vs American made. We don't have a clue what material or workmanship goes into Chinese parts. I'm 80 YOA and broke a pair of Chinese pliers. Please don't tell me the PCM is made in China

Gary: I just checked and PCM and Velvet are manufactured by the same company in South Carolina.

A differing opinion and depends on the mode of failure. I had my 72C rebuilt and uprated (huber marine) when it began to freewheel above 1500 rpm. Broken bronze clutch was the culprit. It came back better than new.

Correct Craft is buying up all their vendors. Hugh wake board boats like pickup trucks for auto companies make big profits

"Gary: I just checked and PCM and Velvet are manufactured by the same company in South Carolina".
That would be PCM see below The old 40 series were made in Italy if I remember correct

In October 2014, Correct Craft acquired PCM Marine Engines, Crusader Engines Inc., and Levitator Performance Airboat Engines which operate together as Pleasurecraft Engine Group.[5][22] Correct Craft acquired Bass Cat Boats as well as Yar-Craft, a walleye boat line owned by Bass Cat, in March 2015.[23] In June 2015, Correct Craft acquired majority interest in Centurion Boats and Supreme Boats, based in Merced, California.[3] Correct Craft acquired SeaArk Boats, an aluminum finishing boat company based in Monticello, Arkansas, in May 2016.[4] Correct Craft announced the acquisition of Bryant Boats, based in Sweetwater, Tennessee, in January 2017.[6]

In November 2022, Correct Craft announced the acquisition of Indmar Marine Engines,[7] the "largest privately held maker of gasoline-powered inboard engines". They supply brands such as Malibu, Tigé, Pavati, and ATX, amongst others. Furthermore, in December 2022, they also acquired Pacer Marine Engineering.

Everyone likes what they like and to each their own. I have put together blue printed race car engines that far exceed factory tolerances and durability.

The most high end engines in the world wether it’s auto, aviation, or
Marine are hand assembled by humans.

I would have no hesitation rebuilding a boat motor as long as I was working with a good shop.

Now buying from a high volume remanufacturer is a different story.
