  1. Removing turbos

    I was wondering, since I'm currently replacing one of my intercoolers (tiny leak) , "why not leave the intercoolers off?" How much HP/efficiency do they add?? 5%??? 10%?? If I don't need the top end HP (I always run at moderate RPM) why have those weakpoints in my cooling system? So what if...

  2. Northern Lights parts?

    A little while ago I was at the boat and in the genny room. I noticed a small puddle of antifreeze on the floor. A quick inspection indicates that the water circulating pump's (Not the RW pump) seal is seeping. I looked in my NL parts manual and I can't help but notice that the seal is not shown...

  3. Crusader Parts

    If the deal goes thru, I will need to replace all risers, manifolds, elbows and hoses on a 36 that has 454 crusaders. Anyone here have a wholesale source to purchase these parts. I have been quoted 2500-3000 for the pair of engins. Seems alittle high to me. Can't I get these parts from my local...

  4. Underwater LED lights

    We installed our LED underwater lights while we had Unity out for bottom painting. They are very well made, require only one 3/16" hole in the hull, and work great. We bought Abysslite lights #600. The cost was $507.00 for three including Florida sales tax. http://www.abysslite.com

  5. Idle RPM Adjustment.. tips needed

    Hi All. My Glendining syncronizer has been shutting it self off at idle. Glendining says the issue is the master engine is idling slower than the slave. My mechanic set them both to about 500 rpm last summer, but I'd like to get the port engine up to 520 rpm to correct the issue if I can. The...

  6. "dashboard" material

    Sorry for the clunky name, because I know the area under the fwd salon windows is not a "dashboard," but you get the idea... Does anybody have any creative ideas for a good material to use to cover over this area? I have some kind of original tan marbled-looking textured formica up there that...

  7. flybridge table materials?

    I wanted to build a table for my flybridge and was wondering if formica if glued well to an epoxy coated marine plywood base would work? I intended to treat the edges with a teak trim screwed and glued with what?

  8. 1958 8V53N rebuild or upgrade

    I am considering the purchase of a 1968 41C Sportfish Hatt that has one 8v53 removed and one in the vessel. The removed one is at a shop that the owner cannot afford to pay for $10K. The other needs clutch rebuilt. The current owner tells me has not been thrilled with the 8V53N's because...

  11. Engine Room Corrosion

    Recently I spoke with a boat owner who has a sedan style boat with cockpit engine room entry. The boat owner equipped his engine room with a dehumidifier that he runs non stop when the boat sits at the dock. The boat is stored in FL and is a 2003. He felt that the dehumidifier helped to reduce...

  13. Muriatic and Oxalic vs phosphoric for H/E

    OK, I screwed up and bought the Muriatic and Oxalic acids instead of the phosphoric. I should learn not to depend on my memory when I'm shopping. That said, can anyone give me the "recipe", i.e mixing ratio, for this approach, now that I have it all and don't feel like exchanging it?

  14. Would changing to smaller injectors save fuel?

    See if this makes any sense: my DD 8v71 Naturals have N70 injectors. I believe that N55 injectors are also available for these engines. Now, '55' is 21% less than '70' arithmetically. Would it therefore follow that I might get 21% more (better) mileage if I changed out to the lower rated...

  16. Salt water strainer before HE or I?

    The current thread on Turbo Replacement got me thinking: I originally removed the intercoolers and had them cleaned because I suspected some blockage..likely zinc pieces from the raw water pump. This forum helped me understand how critical they are as these are the first "TI" engines I've owned...

  19. Fire Supression

    After watching the video links from the Sandbar about a boat fire it got me thinking about fire safety. As I am in a major refit and starting with the ER and electrical, I am now thinking about what type of fire extinguishing system I should put in the ER. The larger boats I have run all have the...

  20. Repower/Engine Removal Question

    Something I was just thinking about....Last repower I removed and installed the engines in the water. This time the boat is on the hard.
