Just got a 1974 Wriedt Spoiler with 455 Olds and berkely jet C. Will be posting more pics on here as project goes along. Jet drive was supposed to have been rebuilt just before boat was put up and sat for 10 years. Would it still be wise to take out jet drive and put in new seals and bearings?? Any comments suggestions welcome!!! More pics later this evening
Very cool boat, classic design.
Maybe you could make sure the bowl is filled with oil and run it easy for a couple trips and see if it is losing oil. Make sure you keep the thrust bearing greased and listen for noise. If it is like the seller said I bet you will be O.K.
