My H400 is 10 years old and I plan to check exhaust gas mixing elbow as that piece is normally the first one to corrode. From outside the elbow looks like new but inside I dont know.  If I open it the elbow's inner tube it may be damaged from inside and I may need to replace it. I checked the price for new elbow before start to do anything and found out there are two alternatiive designs. A simple one, part number 129670-13580 that looks like a pipe and costs 400+ EUR. And a so called high riser type 129470-13541 that looks like a box and costs 800+ EUR. I have the high riser and was told it is normally used if the engine is below or close the water line.  I dont know yet if they are so similar that dimensions would allow me to use which one I like. The engine in H400 is not under the water line although the engine bed is so I think from that point of view I could take the cheaper one. How about you, colleagues that have H400 or other models with Yanmar 3JH4-E. Which kind of mixing elbow do you have in your boats?

I had the elbow in my 10 year old H400 replaced as part of preventative maintenance last year at a unit cost of £820, so I guess it was the high-rise version. Regret I can't say I researched which type to use as work was done by a professional. However, as he's a trusted personal friend I'm confident he'd have used the correct item without exaggerating the need.

Not a cheap game. Good luck!

Rat,

Have you seen the inside (assuming the outside looked good, no rust etc) of the mixing elbow ?

The elbow is stainless, if it looks good it will normally be good.
Accept for crevice corrosion, effects from chlorine,  fatigue etc. stainless doesnít have much secrets.

I.e., was ten preventative maintenance worth it ?

Thanks, Peter

The outside looked OK but I can't comment on the inside as I was far away when the work was done. Yes, the cost was a shock but I'm planning to spend a good couple of seasons in more remote areas so have been replacing all hoses and any item approaching the age when owners start to wonder about it.

As for whether it was worth it, the really annoying thing is that if everything works perfectly you'll never know if you wasted your money! However, while obviously its no guarantee against failure such a refit does bring a certain peace of mind.


All the best

There is an inner pipe in the exhaust elbow. If that is leaking the cooling water can get onto exhaust valve and into cylinder. It is not possible to to predict condition of the inner pipe from the appearance of elbow's surface, but it is also unconvenient job in Hanse to open the elbow for check and the check itself may cause finall damage of corroded parts I guess. It is then as you said a piece of mind issue to change the elbow. Is your SD60 working fine Rock. How many hours now?

scary thought about that elbow failing.

The SD60 is doing fine, now has some 400 hours on it.
But obviously not working any different then the SD50, as long as that works well.

Main plus is that iíll never have the cone/clutch issue anymore and that the SD60 is stronger (rated for higher power), even though I still only have 40HP 😊

SD50 is fine as long as you make a couple of modifications:

1. Vent gear case - remove screw plug from top of the housing and insert 10.5mm x 1.5mm thread hose tail, 6mm or 8mm tail is fine. Run hose to highest point in the engine bay and small airvent on the top of the hose. This vents the gear case eliminating internal pressure build-up while cooling and sucking seawater in.

2. Cone clutch upgrade kit - Purchase cone clutch upgrade kit from saildrives@yahoo.com, this kit replaces brass washers with thrust bearings.

Once done your SD50 will give you years of trouble free service, cost 10% of replacing it with SD60 which by the way also have some idiosyncrasy's as well and is not without its own problems.
