Went out today to test the tachometers and the starboard engine has a fuel delivery problem, it wouldn't go past 2500 rpms even if I kept pushing the throttles and the other engine carried this one so had to turn around. Racors and engine fuel filters are new. I'll replace the racors tomorrow, check...

On page 14 of the Hatteras thread I posted 3 videos.

So just replaced the Faria tachs with the Yanmar tachs and WOT in neutral went up from 3800 to 4300. I confirmed this with the photo tach. So if the readings across the board has the difference of 500 rpms, running WOT should go up from 3100 to 3600. I will seatrial again this week and report back. ...

micky

Alternator output is the least accurate as belt slip will affect the readings. The tach output comes from an ac tap on the alternator and the tach should have that connection marked already depending on the faria model. The tach output on the bellhousing picks up the teeth on the flywheel. As each ...

micky

Anybody know how many poles does the alternator has? Or in which number the pole setting goes? The tach has 6 positions to choose from.

micky

I’m thinking its the tachs. I’m installing the Yanmar tachs today to do another sea trial because the engines dont sound like they are luggin, there is absolutely NO smoke but the 2500 rpm at 18 knots doesnt make any sense.

micky

Just did this and the needle on the tack goes pointing down to 6 o clock and doesnt move.

micky

I just saw it on my engines. I will cut the signal wire from the alternator and connect the sensor in the bellhousing.

micky

How can I know the pulses my alternators produce so I can set the dip switch on the tachometer? I have faria tachometer and Yanmar 315 engines.

micky

Carl!!! I have a surprise for you. She topped out 25.5 knots at 3100 rpm so its heavily overpropped. Top rpm of these engines is 3800 and they have to be propped to reach 4000. These props are Veem Conquest 20 x 20. What hurt is that these props are brand new and I have to buy another set. :? :? htt...

micky

I was able to clean the bottom. Should have a RUNNING update next week.

micky

Still docked. Travel lift broke down last week so couldn't clean the bottom to test engines and props. Supposedly I'm scheduled for Saturday. I'll report back if I was able to do it or not.

micky

Almost had to paint the whole bridge but at least its done.

micky

I had left the bridge cushions in place (for the last 6 months), water got under them and the paint bubbled (the old paint under the new ones). Sanding day one more time. Faired the areas and left it with 545 today. Tomorrow I'll fill a few pinholes and prime again. This never ends!!!!!!!! https://i...

Both engines were installed today and stbd engine was starter and ran for 15 minutes. Port engine wasn't started because I was missing 2 hoses. I already bought them and will install and start tomorrow. Plan is to leave them running for 1 hour tomorrow at idle. They sound VERY different from the oth...

micky

Oil cooler lines were replaced today. Also received the fuel coolers (in the process of painting them) and will install them on Wednesday. After this, install on Saturday if everything goes according to plan.

micky

Decided to paint the engine room as the paint that I had used previously had gone from white to cream. also removed all the paint from the engine beds, primed them with red oxide and painted them white. https://i.imgur.com/rD0FoGC.jpg https://i.imgur.com/zCTHV6C.jpg https://i.imgur.com/62X2yRB.jpg

Sherwin Williams Sher Kem. I was going to buy 1 gallon of Awlgrip but between paint, activator and reducer it was $600 with port supply.

micky

Engines got painted today. Starters, alternators, belts, all hoses and air filter were installed. Plan for tomorrow is to install the wiring harness on both engines. After that need to wait for the o-rings, fuel coolers and oil cooler lines to arrive so I can install them. https://i.imgur.com/ohOVoJ...

micky

Today I scraped all the loose paint and pressure washed them, them gave them 2 coats of primer. I'll paint them tomorrow. I should receive the missing orings this week and can put oil and coolant in them and should have the starters and alternators tomorrow. Oil cooler lines should be here next week...

micky

Started with the tune ups yesterday afternoon and finished today. Did impellers, thermostats, zincs, all heat exchanger, oil cooler, intercooler gaskets and o rings, circulated barnacle buster for 1 hr each engine. You wont believe what came out of those engines. Also replaced the timing belts and 1...

micky

They are finally here. Already removed the transmissions as they wont match my boat but I have the old ones. Tomorrow I'll do their tune ups, remove starters and alternator to have them checked (1 alternator is not charging). Need to pressure wash them good as they have a lot of flaking paint and th...

micky

I'm still here, haven't been able to use a computer as I'm in charge of one of the biggest living complex here in PR and we've been fueling and dealing with generators every day since last sunday.

micky

Paid for the new to me engines today. Now this thread can continue

micky

Kenny sold the engine, so still looking for a pair.

micky

Anybody who could check a Yanmar engine for me? You can text me 787-five 2 five-0 eight 3 two

micky

Spoke to him today, great guy. Thanks.
He only has 1 engine but will find out if he can get another one.

micky

If anybody knows of a pair let me know. Thanks

micky

I have no other option until the issue gets resolved. If it goes to court it will take years.

micky

Need someone to look at a pair of Yanmars.

micky

A few weeks ago the transfer switch from the AC panel went out so decided to move that panel to the main closet under the main panel. Used a 12 x 12 pvc box, installed a main panel with transfer and a voltmeter on the side (still waiting for it). Then looked at the main panel and said " I can remove...

micky

The issue is this Yanmar block are an alloy of aluminum and teflon. Plus I paid for good engines not this POS.

micky

Things took a turn for the worst. Yanmar mechanic went today to check the engine and found that the block is cracked on the inside, on the outside the other guy used epoxy and painted over it. Also found that 1 of the rods was ground down with a grinder. Also all the rods were cut where the blue cir...

micky

Still finding issues: In between the block and bearing cap there is an oil passage for the sump, in between the block and bearing cap it uses a gasket (see pic of manual) and the guy installed an o-ring.... https://i.imgur.com/VmMJ5Av.jpg https://i.imgur.com/ljuzmDL.png https://i.imgur.com/FEZ7jYE.j...

Finished the teardown today and ALL bearings are bad. Mains and rod. Rod bearings (6) https://i.imgur.com/mcF9OjP.jpg https://i.imgur.com/q9aKVqQ.jpg https://i.imgur.com/vAyYjke.jpg https://i.imgur.com/nSFg7tY.jpg https://i.imgur.com/Eflmu2A.jpg https://i.imgur.com/afJGPPa.jpg Mains https://i.imgur....

micky

So took the engine out of the boar this morning and took it to my dads shop. Started disassembling it and found that the rear seal is old, the gasket for the turbo oil drain is old, the gasket for the front of the engine (cooling system) is old. All the front gears are new and were installed correct...

micky

My dad told me today to take the other engine out as soon as I put this one in so…..

micky

I think about the other engine every day and if I had money to spare I would pull it out also just to check but that one is working fine, 50 psi cold, 30 psi hot.

micky

My lawyer (Hueso) has been guiding me in how to play this.

micky

Mechanic was supposed to come yesterday to check the engine and never arrived, then he told me he was coming today and he cancelled so I’ll disassemble it myself, order the parts, take the crankshaft to a machine shop and will hire a Yanmar mechanic to assemble it back.

micky

He did told me that he will take care of the situation and that if his work failed he will take care of everything. I know it did. My plan is to take a few vacation days and be present when he's asembling everything.

micky

I'd be tempted to plasti-gage the crank and rod journals before moving forward. Does plasti-gage still exist? it's been a while for me. Anyway , the point is to understand the fit, or clearance, between all the journals and all the bearings. Still exists and the service manual says it HAS to be used.

micky

If you see pics 4 and 5, the black dot is dirt embedded into the bearing. 2 and 5 are extremely tight. I didn't have a breaker bar with me yesterday.

micky

Spoke to the mechanic today and showed hm the pics I took yesterday, he asked if I could take pics of the bearings so I did that, I was able to remove cylinders 1,3,4,6. Cylinders 2 and 5 I was unable to loosen them up. Cylinder 6 I was able to loosen the bolts with 1 hand and without doing any kind...

micky

If he did touch the bottom end then he never had the crankshaft checked to see if in specification. Anytime you pull an engine apart and you are just not sure of how it was running before you ran it then you MUST have the crankshaft checked. Micky you are warrior with this project and in the end it...

micky

Thats what my dad said.

micky

Took the engine out yesterday. Removed 2 of the pistons bearings, bearings are new, but look at the condition of the crankshaft. When I did the oil test the main bearing leaks like an open faucet. Look at the pic with the blue arrow. Another thing is, look at the bolts, black oil, smelled like burnt...

micky

Engine has to come out, bearings are leaking BIG TIME. I’ll post the video later tonight.

micky

I haven’t contacted them again as I wanted to see if the spring and relief valve fixed the issue. I’m dropping the oil pan on saturday and doing the oil drop test, if its the bearings I’ll give the guy a call. If its not that, it should be the oil pump.
