Re: Yanmar starter relay
Thanks for asking. No, after 7 weeks, the intermittent start issue is still happening. We are still pursuing it. We have tested and ruled out the ignition circuit. There could still be a chance of an air leak, but we have done a lot to reduce that possibility. Our target now is the injectors. We pla...

Re: Tightening Alternator Belt
Agreed, Duane. You may be right that there is a lot of leeway on how to tension a alterantor belt. However, I don't feel like I'm seeking perfection by a long shot. I'm just baffled when a traditional rule-of-thumb (literally and figuratively) appears so out of sync with the guidance from virtually ...

Re: Tightening Alternator Belt
The issue I've routinely bumped into is the difference in tension required for a serpentine belt vs. a V-belt. I believe Yanmar assumes the boat owner has the original 80 amp Hitachi type V-belt alternator. Well, I have that kind on my STBD engine only. I have a Balmar AT-165 amp alternator on my PO...

Re: Tightening Alternator Belt
Yes... I'm actually going to get and try two tools: 1) Supco adjustable Belt Tension Jack <t.ly/o_gd> and 2) Gates 91107 Krikit Tension Gauge <t.ly/p5V3>....

Re: Tightening Alternator Belt
Thanks for the replies. I do understand the “thumb” technique. That’s what l’ve been doing. I don’t understand why so many people ignore the Manufacturers recommendation on this when it is so important for optimizing the efficiency of the alternator and avoiding damaging the bearings in the water pu...

Tightening Alternator Belt
I replaced both of my alternators recently with refurbs. Both were acting wierd and when bench tested were rated as "close to failure". Two questions... First, what do you use as a LEVER to hold the alternator in place while you tighten the bolts. It seems like it takes 3 hands and some ki...

Re: Nova Kool Refrigerator
What I recall is the following: Doug, When I looked the cutout specs and thought about how it would fit the space, I concluded the ONLY way to fit the fridge was to expand the cutout ONLY on the RIGHT side by about 0.25"... maybe a touch more. Be very careful to note the exact location of the 3...

Re: Impeller or the whole pump? (If you have spares)
John, could you clarify how you actually change the impeller? By that, I mean... how to do actually reach and remove the impeller? Are you actually able to reach back there with one hand and blindly remove screws & cover, remove the old impeller, insert the new impeller and replace the cover and...

Re: Yanmar starter relay
Thatks a very interesting possibility, John. The engine started normally for the last 4 days (we have not started up yet today). I did find one more hidden fuel hose clamp yesterday that allowed more tightening than the others. We’ll be back in port on Wed and I plan to meet with our diesel tech guy...

Re: Yanmar starter relay
So far, I'm buying into the "Air Leak" theory as the cause of my intermittent start issue. The battery is strong. It cranks (strongly) on turning the key to START. The only other speculation someone suggested is the fuel "lift" pump. I don't know anything about that pump (it's be...

Re: Yanmar starter relay
What are the typical symptoms of this relay starting to fail? Or is it simply a Go or No Go kind of device? I started experiencing a fairly consistent pattern of my port engine being hard to start. It went from always starting after ONE second of cranking to suddenly 3 weeks ago not starting after m...

Re: Dry Bilge
Nick, what’s you describe sounds excessive for water leakage to me. We have PSS “dripless” shaft seals. One has almost no water leakage at all.. to the point where I thought it might be set too tight. We’ve had it triple checked. The other PSS shaft leaks what I’ve learned is a normal amount.. about...

Re: Fuel transfer pump
Hmmm. I've seldom transferred fuel from my Main tank to the forward tank, but when I have it has seemed to go at about the same speed both ways. One possibility to condsider is microbial growth in your fuel lines and tanks. Do you ever add a product like ""Biobor JF” to kill algae that can...

Re: tach guages
Interesting. I get how the RPM data shows on a multifunction panel. Do you have a picture of your flybridge helm showing where you added the temp and oil pressure gauges for both engines?
