    3988 ...almost there-gctid366218

    Hi all, I am making an offer on a 3988 today .... Yay! I found a really nice freshwater boat from a retiring boater.

    Question regarding the W06 Hino .. Both the 250 and 310 are basically the same engine I believe, so the stress on a 250 should be less than the 310 at similar rpms? What rpm do most of you use for fast cruise?( this boat has the 250) I normally cruise in the slow lane but occasionally will need to go faster, perhaps to help out handling in a following sea etc.

    Other question I had is the swim grid on this boat is in the low position. Does it drag water at cruise speeds? I know about the water absorption issue and will check it out on the survey, just wondering how critical it is to have it raised up?

    Thanks very much

    Congratulations on the new boat - much luck and happy boating ahead.

    "Question regarding the W06 Hino .. Both the 250 and 310 are basically the same engine I believe"

    Same engine family but there are some real differences including pistons, oil capacity, oil pan, filters, etc

    These engines should serve you very well if you prop the boat to achieve 3,000 rpm's +3-5% at WOT fully loaded (short test) on a hot an humid day.

    Making sure that the tachs are reading correctly and no other symptoms show during this test.

    Extra 'insurance' can easily be gained by adding pyro and boost gages if they are not already installed.

    After insuring your max rpm's loaded any cruise speed that utilizes 10gph or less per hour per engine would be fine for a long life.

    If you can achieve approximately 3,100 rpms loaded then you can run at about 2,800 fast cruise as that will be near 10gph.

    After proofing the engines and purchasing the boat consider 'baselining' the engines by recording all gage readings and speeds in chart form and/or by digital photos for later comparisons over time.

    Hope this helps

      Congratulations on your new baby. It is a great boat. I would definately have the swim step raised if you are boating in coastal waters. I would hate to think what the stresses are on it in a heavy following sea, especially if you are supporting a dinghy on it. Ours is located at the higher level, and even then it sometimes becomes slightly awash, depending on sea conditions.

        Well, offer accepted, now having mechanical and survey done on Monday and Tuesday. Sea trial will be in Lake Washington.

        After completion , on the way home I am stopping by LaConnor for a hardtop intallation.

        Going to have to change my avatar!

            Congrats!

            The 3988 is a great design!

            The hard top will be a big addition. Get out of the rain, and have a good place for the skiff.

              While in LaConner have them install the two side hatches in the cockpit for additional storage. You will not regret it. Larger stairs are nice also. Flybridge storage has not been a super used item for me.

                We are picking up the boat at the end of the month, can't wait!

                One thing I would like to change is the seating on the flybridge. I would like another command chair along side the original setup. I really like having the Admiral sitting with me underway and an extra set of eyes is good as well. Has anyone added another chair on the bridge? , any advice on removing the headliner to access thru bolts or just pot some nuts into the balsa coring?

                Thanks for any help

                  I wouldn't rush to put in the extra helm chair. Try it without and you can always add one later if that's a better plan. One consideration is a large cooler to be used as combination storage, a table and a 2nd helm seat. MY co-pilot is quite comfortable using the stock seats, says she is comfortable and can see well.

                    Congtrats on the new boat from us also. I agree about waiting for the new helm seat. We put a pair of big, thick, furry, cushy, square doggy beds up front on top for the wife to lay on next to the front windows and in the sun while we cruise...

                    You will enjoy that new hardtop too.. More living space..

                      We put a 2 helm chair on our 3988. The admiral loves it and would not be without it. I was very careful on placement, so I can move side to side without any problem.

                      Found it at Royal City upholstery for $300 last year

                        How did you mount the second chair to the sole? Thru bolt or ??

                        Thanks, Gary

                          We also put a second helm seat in. 2 people watching for logs is alot better then 1. You are welcome to come and take a look a our 3988 and I could show you were you could put a extra water tank that you talked about. Send me an email and I will send a phone number.
