Volvo MD2030 Exhaust Riser/Elbow
Does your engine suffer from lack of power, unable to obtain maximum revs?
We bought a “pre owned” Maxi 1100 – “Maxi Magic” from SD Marine. Whilst she is a very quick boat under sail, the same could not be said when she was motoring. Having sailed through most of the boats out in
We had noticed that we could only get a maximum of 2800 RPM out of the engine under load, where as on our previous boat, a Maxi 34 “Eye of Horus” we could get 3400 RPM. The difference in RPM was initially put down to only having a two bladed fixed prop on the 34 as opposed to the three bladed folding on the 1100 and an extra two tons weight difference. Based on our engine experience with the Maxi 34, I took the opportunity in the autumn to remove/inspect the exhaust riser. Having removed the riser it was no surprise to find that approximately 1/3rd of the inner sleeve (where the raw water mixes with the exhaust gas) had corroded away and the main bore had been reduced from 35mm diameter to 7mm diameter (see photo – just enough to get a pencil through!) by the build up of carbon and salt.

Outlet-Old unit with corroded water gallery New unit
In my opinion there is no point in trying to salvage a riser in this state so it was off to the local Volvo agents for a new one (£160 plus £4 for the gasket). (Looking around the internet I did not find any at a materially better price). If you do try and clean/salvage an exhaust riser be very careful of the inner sleeve/water gallery, as although it may be intact, it will probably be rotten and will break up if any force is applied to it.

Having fitted the new exhaust riser we took her out for a sea trial and at full throttle got 3350 RPM. That should be enough to see off the other boats motoring back into
On a more serious note, I would recommend that you check the exhaust riser after say 600/700 engine hours (Maxi Magic had done 1100 hours). I considered getting a stainless steel riser fabricated, however, apart from the estimated cost (£250), talking to other people about their experiences with stainless risers, the sulphur in the exhaust corrodes the stainless and stainless cannot absorb the thermal shock (cold sea water and hot exhaust gas) as well as cast iron. Also when stainless cracks you will get a hole whereas cast iron will tend to weep.
Removing the exhaust hose from the riser is a bit of a chore. I used a blunt screw driver and gradually worked it into the joint, taking care not to tear the rubber pipe, and it took about 30 minutes to release. To make it easier to remove the hose in the future, I wrapped the outlet of the new riser in PTFE tape.
Having checked our fuel consumption, this has improved, and the tiny bit of hunting that we had at tick over has now gone. A job well worth doing.
