From the Beta Website :- https://betamarine.co.uk/inland-accessories/ Look in the engine accessories section.

There are some canal walks in Staffs. here. https://www.walkingenglishman.com/staffordshire.html As you live in Eccleshall which is inside the 4 counties ring I suggest that you look at Pearsons Canal Companion '4 Counties Ring' & Nicholsons '4 Counties Ring'. You can get them online or from the Anglo Welsh hire base at Great Hayward or Canal Cruising at Stone. Pearsons would be my first choice.

Rimmer Bros. also stock the sump gasket for the 3 bearing BMC engine for about £2.

If it's the same as the 1.8 then Rimmer Bros have gasckets. https://rimmerbros.com/Item--i-GRID000357

There's one at the Red Bull services on the T&M. Never seen anyone plugged into it though.

I suspect you meant 1500 metres.

I think you slightly misunderstood my post. I suggested that the op contacted Barrus to get the proper manifold as Barrus are the agents for Yanmar marine engines. The 4JH is a proper marine engine built entirely by Yanmar. I don't see any harm in asking Barrus about a Shire 45 manifold, they can always say no.
