MTU 16V2000 M91 full rebuild; in vessel

It’s very clever ( space permitting) the guys have been able to rig a hoist to lift it , invert it , re rotate it back and block it off as they wish …..all in situ .
Great thread btw .Pic threads always all Thx .

Thank you Pascal!
Images are great.

Imagine that's to keep motor compact in size "relatively "

Oh is that all it takes? Looks easy!

Very,very impressive. Thanks Pascal

All comes down to when you hit that ''Start'' button again. Hope all goes well. Sound like they did a great job on the first motor, should be the same result on this one.

MTU major service intervals are W-2, W-4, W-6 / 2,000-4,000 & 6,000 hrs. 2,000 hrs. are injectors, pumps. coolers and turbo service. 4,000 hrs is W-2 plus heads off and valve train replacement. 6,000 hrs is W-2 & 4 with cams and crankshaft replacement, pistons and con rods, new turbos and new coolers and pumps. Seem like Pascal is doing a W-6 at 4,000 and when the owner decides to sell, this vessel will much more appealing to buyers and the sales price will reflect this major service done early. I know the cost of performing a W-6 on 4000 series & would venture that this service easily tops $250,000 on the 2000 series.

With MTU service intervals completed it will mean the difference between a sale or no sale for a yacht. Many a large yacht have lingered for years on the market with 6,000 + hrs. due to the previous owner not wanting to spend 1 million $$ + to perform w-6 service on twin 16v-396 tb-94 or 4000 series engines. Once these major W services have been completed the owner will recoup monies spent in the asking / selling price. This scenario isn't anything new and has been proven over and over through the years with MTU's installations.

Just signed paperwork for cat c32 ex warranty platinum plus total coverage 5 yr, 6000 hr new motors, $13k each motor

I understand your position on proper maintenance and would venture to say were not talking apples to apples here. Oil and filter changes are proper maintenance on normal engines where a Jabsco raw water pump costs $3,000 dollars or so and an oil cooler might be $5,000 and the service regiment recommended by the manufacturer is followed but the MTU upper service regiments and exorbitant costs of W-4 and W-6 service make owners eyes water with the $$$ involved where Raw water pumps cost $13,000 + coolers $36,000 and on and on. To give you an example. An immaculate and highly maintained 1987 40-meter Abeking and Rasmussen was on the market for sale a few yrs. ago with an asking price of 5.8 million with no takers due to W-6 service needed on triple 16v-396 engines at a cost of $3 million plus for the service. The yacht sat stale on the market for sale for over three years with plenty of interest until the issue of the W-6 service was brought into the picture. The owner kept dropping the price every 6 months until it was down to $700,000 still with no takers and he was finally considering donating the boat due to his new 53- meter Delta Marine being delivered. Being who this man is and his love for his long-held yacht he finally bit the bullet and had the W-6 service performed on all three engines along with an engine room re-spray in Awl-grip and some minor cosmetic updates in the rubber band room and the boat sold within 60 days bringing his original asking price or very close to it. This is the same man who held the leases on the WTC when 911 happened and the insurance companies didn't want to pay for either tower due to an act of terrorism. Not only did this man prevail and beat the insurance companies but received compensation for both towers as two separate acts of terrorism causing underwriters to rethink / re-write their policy terrorism clauses. Even the smartest financial minds break at the thought of scheduled MTU W-6 service on their beloved yacht that they've enjoyed for several years but know that either the design or style is long in the tooth and they're looking to upgrade to the next purchase or build a new vessel and are reluctant to make the capital investment knowing that the next boat for them is on the horizon and they would rather pass the expense of W-6 service to the new owners. This but one example out of many where an owner recouped his W-6 service investment when selling his yacht. Maybe it's just a MTU thing.
