I am buying a Trophy boat froma dealer with a mercury 15 hp 2 storke dated 2000. They have agreed to go over the motor for me before purchase and fix or replace anything that needs it. The boat is a year 2000 and they are claiming under 5o hours total use. Is there specific things I should have them replace like water pump, spark plugs, lower end unit oil etc that are out of date even though it has low hours. What should I be having them specificaly due. I am treating it like a wish list. Any thought would help, thanks Rand

Definitely have them put a new waterpump in. I would also change out the tstat if has one.

If it is running the least bit rough I tell them to rebuild the carbs and fuel pump.

Thanks, for quick reply, Rand

I think you named off the imortant things. Have them do a compression test as well.

The 2000 Trophy with 150 Merc. is a good combination as I own one. It's important that you have the head gaskets, t'stats, impeller and poppet assembly replaced. After these repairs, run the boat and check the speedometer and gas gauge; both give problems. I would also have a temperature gauge installed; you'll be glad you did. Check the oil tank bracket for corrosion; have them replace it if corrosion is visable otherwise, you will replace it later (not very sturdy).
If the trophy is a center console, have water put in the 2 fish boxes at the transom port and starboard floor. Make sure the water drains properly into the center bilge tank. If not, have them correct the drains (factory installed up-hill drains-not to efficient). The boat and motor are excellent other than the mentioned points and runs well offshore or inshore and is excellent on fuel.

thanks again, all very helpful, keep it coming if you got it> Rand

PS, what would a bad result of a compression test read? Rand

[rand5g]

it is a walk around....if that helps...Rand

With the cylinder block warm, battery fully charged & throttle shutters wide open, you should have between 110-135 psi (733.3-924.5 kPa). Variance between cylinders should not exceed 15 psi (102.7 kPa)

[rand5g]

Should the tech be able to give me the results for compression or is that asking too much?

[ncfish1]

Absolutely! I would ask for the results of each cylinder test and then compare the results with what you know it should be. If you see that you are within the acceptable tolerances, then you should be safe with the motor operation (at least with the compression question).

Thanks for all the help!!!! I will post what comes up, thanks Rand

tech can give you any results he wants.it is best to be on hand to see the results of the compression test yourself.this will eliminate a shaddy deal,and a reputable dealer shouldnt mind atall.
