okay...good news, she's wet, and runs like a champ. ;D
we were supposed to do a sea trial on friday, but the folks that were supposed to put on prop speed didn't show up until friday afternoon. got her wet on saturday, and 2 mechanics and i took her for a spin, and did the sea trial. actually had her wide open for the majority of the way from annapolis to kent island, and she ran at 38k! i never run wide open, so that was quite fun.
they told me to make certain i vary the throttle on longer trips, so i spent the weekend going from 2800 to 2000 to 3200 etc. we put a bunch of hours on the new engine, and i haven't had any issues other than the idle settling in a bit too low. they'll get that squared away this week...then i just need to have an initial service at 50 hours, and i should be all good.
all in all, it was a fantastic weekend. don't know if it was the perfect weather, all the great stops that we squeezed in, or just being back on the water. i'll take it either way...
thanks for all the help, and advice along the way. i'll keep you guys up to date on who helps out/doesn't, and what the final diagnosis ends up being.

I would like to know how prop speed holds up. I have been thinking about it. Does your boat stay in the water year round also? When water is warm I have diver clean every 6 weeks. Glad to hear that you are up and running. That was a quick turn around. Hope you get some reimbursement.

This is the first time i've used prop speed. last year another yard used a pettit spray paint to coat the props and shafts...i couldn't remember what it was though, and bay shore recommended prop speed. i do leave her in year round, but you have to remember that i spend most of my time in fresh water, so i probably don't have it as bad as you guys do. 
with any luck i won't be hauling again until next year, but i'll try to remember to post a follow up.
i did take some shots of the props before prop speed, and after it was applied. only took about 15 minutes for them to paint it on, but two of them worked on it because they said you have to work quickly.

uh.........will i look stupid if i ask what prop speed is? looks like some kind of coating. what is it supposed to do? is it recommended for fresh water? and can it be put on any kind (bronze,nibral) prop?

yep, coating...usually for boats in "foul" water that are in the water for an extended time.
here is what propspeed says ---
Anyone who is concerned with excessive fuel consumption, the increase in potential engine-fatigue, the increase in running-gear maintenance and their associated cost. No vessel is immune. Be it a tug-boat, naval ship, sailing yacht, motor yacht, fishing boat, or cruise ship! Today?s boat-owner would never consider launching his vessel in heavily fouled waters without protecting the bottom. The protection of the running gear is just as important for a vessels long-term performance. Why Use PropSpeed?
Boat-owners, captains and marine surveyors all agree that a vessel that?s just been launched with a clean bottom and clean running gear will run at peak-performance. Unfortunately that peak-performance running time can be short-lived due to the heavy build-up of marine growth. PropSpeed will assist in maintaining maximum vessel performance while allowing the running gear to do what it was designed for: Slice through the water with the least amount of friction generating the greatest amount of thrust. The Barnacle
Tiny barnacles and marine organisms that attach themselves to a boat?s propeller and running gear can wreak havoc on a boat?s performance, fuel efficiency and maintenance requirements turning the joy of boat ownership into a nightmare. These barnacles, algae and marine worms can grow right on the paint, and some actually eat through the paint and attached themselves to the underlying bronze exposing it to the additional corrosive effects of saltwater. Cavitation
Propellers move a vessel forward by pushing water aft in a spiral funnel pattern. Fouled propellers rapidly loose their efficiency by inducing air bubbles into the water funnel. This is known as ?cavitation.? Additionally, fouled propellers can go out-of-balance causing undesirable vibration, resulting in increased wear on the shaft, cutlass bearing, transmission and other engine and drive-train parts. This too can substantially increase maintenance cost. PropSpeed Benefits
PropSpeed is the most cost effective way to keep your boat running at peak performance.
Boat owners and captains report 10% fuel savings and increases of up to 3 knots in speed over the life of a PropSpeed application. Most marine-growth has a difficult time adhering to the coating and simply slides off the running gear every time a vessel runs. Additionally, PropSpeed is environmentally friendly. It contains no toxic chemicals or harmful pollutants. It works because it?s slick, not because it?s toxic likely most bottom paint.

hey Todd whatever became of this? i was following along and last i remember there was a rod bolt failure of some sort. what did it end up being and did you end up getting any help with cost? and by the way, that sure is a pretty boat!

hey FT,
well, insurance company did all kinds of analysis...i'll spare you the details...and came back and said that they think the bolt that holds the cap on the crankshaft was improperly torqued, and it gave way first. i'm still waiting for the reports which drew this conclusion...then i'll go from there.
in the meantime, i got the insurance guys to agree to a quote for a new engine since everyone agreed that the old one was trash. once i got that, i had a new engine installed in about a week. the boat's been back in the water since the beginning of september, and i've been using the heck out of it.
so, i continue to fight with insurance, and mack boring about this thing, hoping someone will step up, but it doesn't look good. i've already footed the bill for all of the work, and now i'm just hoping to get reimbursed. at least i'm out and enjoying it while i still can.
thanks for the comments on how good she looks. i take a lot of pride in keeping her clean, and 5 weeks on the hard gave me lots of time to shine her up.
take care,
todd

Did Yanmar ever get a chance to look at the engine directly ??
How would your insurance on the boat cover something like this ?

wow, i can't believe that it's been almost a year since i started this post. i really can't believe that i haven't looked at it in forever!
FanMN, i apologize for not answering your q's. one, i had bay shore marine doing all of the work, and Mack Boring (the Yanmar distributor) never wanted anything to do with the engine. i actually got them to submit a request for assistance, but it got denied. the answer i got was that the folks at corporate in japan were rather hardline on the warranty claims, and since my engine was out of warranty, they'd want nothing to do with it. MB did offer to purchase the block back though...so i'm working on that.
my insurance has a few neat lines that apply to this scenario. it states that it is not responsible for any mechanical defects, but that it will cover any subsequent damage caused by the mechanical defects. so, my best hope was to prove that the bolt that failed was indeed a mechanical defect. if that had been the case, then insurance would have covered the cost of the engine less the cost of the bolt. so, the insurance company worked diligently to prove that the bolt was improperly torqued. this means no mechanical defect, and no coverage for subsequent damage.
to wrap this up...i looked into legal action. my best option would have been to get my own metallurgist, and engine specialists to argue against the insurance company. after looking at their fees, lawyer fees, etc...i didn't know if i could even break even. so, i decided to concentrate on enjoying my boat.
good news is that i have over 100 hours on the new engine now...did i ever mention how much we love using the boat??? everything is going well with both engines, and i'm confident we'll be just fine. thanks for all of the help getting through this, as it was a royal pain. i got calls from several of you guys, and i appreciate all of the advice and support.
looking forward to seeing all of you on the water this year!
