Just thought I’d introduce you all to the Merc 20 I purchased from AndyB a few weeks ago.
Despite promising Mrs Nasher I wouldn’t touch it until I’d finished the new family bathroom, I managed to have a quick play today
The Smaller Nashers want to upgrade their 2.8M SIB this year to something slightly bigger, and currently have their eye on a Bombard Aerotec 380, so if anyone knows of one at the usual Nasher type price, ie cheap, please let me know.
They want a small RIB really, but I want to be still able to roll their boat up in the bow of ‘The Nashers Revenge’ to transport it round to the beach before blowing it up from the electric pump in the console.
Anyway, back to the Merc, which is earmarked for their bigger SIB.
It was an absolute bargain from Andy, so thanks very much.
It has loads of compression, and selects forward and reverse, but I’ve not tried starting it yet as it needs some work.
Cosmetically it will be subjected to a full make over on the outside, but under the hood it’s in exceptional clean condition.
One thing is for sure, I’ll be restoring and using the spare set of much earlier ‘Thunderbolt’ Red in colour bodywork that came with it, as we all think it looks much better than the Blueband stuff.
From what I read, and what I was told, the drive shafts on these engines have a habit of rusting themselves into the crankshaft, making the bottom end impossible to remove to change the impellor, and that if I could get the bottom end off the engine was worth saving, if not it would only be good for parts.
Despite the shaft itself being very rusty, some previous owner had obviously had later removal in mind when he greased the splines, and the bottom end came off that easily that it would have broken my toe had I not caught it when I did.
The water pump is obviously in need of a new impellor, gaskets etc, but the housing and base plate are in good condition to re-use. Currently the impellor is stuck firmly to the shaft, but I’ll give it a spray of release agent occasionally and try again in a few days.
Looks like I’ll be flushing, cleaning and painting for a while, but it looks like it will be worth it.
