50 hour service on 2014 Cutwater 30

[dialtone]

It's time.... I'm so excited. New oil, tighten some belts, clean some strainers.... This will be my first 50 hr service. Any advice on costs? I'm thinking a few hundred dollars up to $500 if no problems are found? Will be using a certified volvo mech of course (referred by dealer). I'll let you know how it goes.

Make sure they check the shaft alignment and that must be done while the boat is in the water.

On the R29 my oil change runs around $800.00...400 parts/400labor....I did the math and given the amount of time and pain it would put me thru ... $400 in labor is a bargain. I'm having the main engine and the genset (oil and impeller) done in two days...my wallet is allready screaming

Good advice on the shaft alignment. I read the D6 service manual and would have missed that. Just curious, how does one see/test if the shaft is in alignment?

The shaft alignment only needs to be done on the first service. After that only if you have a vibration problem or if it shows up on the maintenance schedule.

The check is done one of two ways:
The most common is with a feeler gauge. A line is scribed across the coupling. (so it goes back the way it comes off)
The coupling bolts are removed and the the space is measured with the feeler gauges. If all measurements fall within Specs the shaft is rotated until scribe line is lined up, the bolts are reinstalled, and torqued to spec.

The other way is with a computer shaft alignment system...very accurate and very expensive.
We got one where I used to work. With 1,000+ motors and gear boxes it paid for itself immediately in electrical costs, down time and equipment replacement.

Called Rincon Marine for the 50hr service. They don't offer shaft alignment service. Sounds like I need to find a boat yard. I'll definitely look into this. I'll report back on my 50hr service once complete. Current ETA is 3-4 weeks.

Had my main engine and the genset serviced. Darn good thing I had the genset done.The impeller had two broken vanes and the rest were cracked. The technician fished the broken rubber parts out of the heat exchanger and flushed it. That would have been a bummer when it overheated on my next trip. For those in So.Cal. I strongly recommend Coast to Coast marine in San Pedro. I have absolutely no affiliation with them but they know the Rangers inside and out and do a fantastic job.

it's very good that they found the broken impeller pieces before they migrated downstream and caused big overheat problems. we once fired an impeeler ina raw water pump ona yanmar. the pieces migrated into the heat exchanger where they blocked raw water counterflow so badly that the engine temp spiked to redzone any time we were over 2000 rpms. it took a week of dissembling the whole raw watercooling system before we fished the little black rubber bits out of the heat exchanger. we are in an area where the closest diesel mechanic is 100 miles away at 100 an hour including travel.. with up to 3 weeks wait for an appointment. so we have owned the yanmar dealer service manual, parts manual and install manual for all 3 of our engines.

now, i run a 30$ infrared thermometer on the block , thermostat fitting and exhaust hoses and record the readings in a log . any significant upward deviation to the temps at the same rpms makes me suspicious that i have thrown an impeller blade or possibly blown a thermo stat...

fair winds, cool running to you
