Twin Crusaders

My first post here. I am looking at buying a 40 ft. Silverton. It currently has twin 1986 454 Crusaders 350 I believe. The broker reports appox 500 hours on the engines. Don't know what he is counting from (rebuild, original, or repower) He also reports that one of the engines has a problem, specifically water in the engine oil. I am going to see the boat this thursday. What should I be asking or looking for, as I have never owned one of these engines. What type of pre purchase tests would you recommend. I plan on at least compression, maybe oil analysis, not sure about that since there is already water in the oil. In short, how would you folks proceed regarding the engine. Thanks.
 
Welcome to ME.com!

I would say go find another boat as it is a buyer's market and there's no reason not to get one that is turnkey, without any major engine issues.

You should also consider hiring an accredited marine surveyor to go over the boat before you "invest". Good ones are not cheap but worth every penny.
 
You don't say what year the 40' Silverton is or what the asking price is but the 40 footer is a lot of boat (about 24K # dry) to push around with those 454's...cruise speed with probably be around 15mph and costly. A good SAMS or NAMS accredited surveyor as mark suggests is one thin but a good mechanic to check those engines (and generator if so equipped) is also a must. Stepping into a boat with a known water in the oil issue may mean a replacement engine is in the very near future so unless the price is great and reflects what is needed to put it in better than turnkey shape, look elsewhere.
 
which model silvverton conv or aft cabin if the water has been in there for more then a week the engine is shot only rebuilt engines are available or there are some new Mexican blocks The conv is easier to replace engine open salon door lift floor lift engine out aft cabin the manifolds need to be removed and much harder to get out thru little door to salon. Usually water in engine due to bad riser secondary to lack of maintenance(Hint whaqt other maintanance not done) also what is status of gas tanks if original plan on replacing them to so if you replace engines and tanks u will have nice boat but you will never get back money you put in for repairs

Hire an accredited marine surveyor! Don't even think of "saying" money here.

No other info or advice is needed.
 
If the boat is also 1986 and 1 engine is bad then I would say has close to zero value, maybe 5k. If you are handy and do the R&R yourself and plan on keeping the boat long term then it may be worth buying for short $. In excellent shape the Silverton 40 footer are worth 20-30k tops.
